Question: NGC is a galaxy in what constellation that refers to a sea monter in Greek mythology?

Context paragraphs:
Cetus: Cetus ( ) is a constellation.  Its name refers to Cetus, a sea monster in Greek mythology, although it is often called 'the whale' today.  Cetus is located in the region of the sky that contains other water-related constellations such as Aquarius, Pisces, and Eridanus.

NGC 3626: NGC 3626, also Caldwell 40, is a medium-tightness spiral galaxy and Caldwell object in the constellation Leo.  It was discovered by William Herschel, on 14 March 1784.  It shines at magnitude +10.6/+10.9.  Its celestial coordinates are RA 11 20.1 , dec +18 ° 21′ .  It is located near the naked-eye class A4 star Zosma, as well as galaxies NGC 3608, NGC 3607, NGC 3659, NGC 3686, NGC 3684, NGC 3691, NGC 3681, and NGC 3655.  Its dimensions are 2′.7 × 1′.9.  The galaxy belongs to the NGC 3607 group some 70 million light-years distant, itself one of the many Leo II groups.

NGC 384: NGC 384 is an elliptical galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "pretty faint, pretty small, southwestern of 2." , the other being NGC 385.  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 384 forms a galaxy cluster called Arp 331.

NGC 908: NGC 908 is an unbarred spiral galaxy in the constellation Cetus.  It is at a distance of 60 million light years away from Earth.  NGC 908 has vigorous star formation and is a starburst galaxy.  The galaxy has three-arm spiral pattern, with two arms with peculiar morphology.  The central bulge of the galaxy is bright.  Cluster of young stars and star forming knots can be seen in the arms.  Starburst activity and the peculiar morphology of the galaxy indicated it has a close encounter with another galaxy, although none is visible now.  NGC 908 was discovered in 1786 by William Herschel.  Two supernovae have been observed in NGC 908, SN 1994ai (Ic type, mag.  17) and SN 2006ce (Ia type, mag.  12.4).  It is the main galaxy in the NGC 908 group, which also includes NGC 899, NGC 907 and IC 223.

NGC 375: NGC 375 is an elliptical galaxy located in the constellation Pisces.  It was discovered on September 12, 1784 by William Herschel.  It was described by Dreyer as "pretty faint, small, round, brighter middle."  Along with galaxies NGC 379, NGC 380, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 375 forms a galaxy cluster called Arp 331.

NGC 68: NGC 68 is an lenticular galaxy, and the central member of the NGC 68 group, in the constellation Andromeda.  The galaxy was discovered on September 11, 1784, by William Herschel, who observed the NGC 68 group as a single object and described it as "extremely faint, large, 3 or 4 stars plus nebulosity".  As such, his reported location is between NGC 68, NGC 70, and NGC 71.  By the time Dreyer looked at the galaxies to add to the NGC catalog, however, he was able to tell that the single galaxy observed by Herschel was in fact 3 adjacent galaxies, and cataloged them as NGC 68, NGC 70, and NGC 71.

NGC 385: NGC 385 is a lenticular galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "pretty faint, pretty small, round, northeastern of 2." , the other being NGC 384.  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 386, NGC 387 and NGC 388, NGC 385 forms a galaxy cluster called Arp 331.

NGC 297: NGC 297 is a galaxy in the constellation Cetus.  It was discovered on September 27, 1864 by Albert Marth.

NGC 380: NGC 380 is an elliptical galaxy located in the constellation Pisces.  It was discovered on September 12, 1784 by William Herschel.  It was described by Dreyer as "pretty faint, small, round, suddenly brighter middle."  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 380 forms a galaxy cluster called Arp 331.

NGC 388: NGC 388 is an elliptical galaxy located in the constellation Pisces.  It was discovered on November 4, 1850 by Bindon Stoney.  It was described by Dreyer as "very faint, small, round."  Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386 and NGC 387, NGC 388 forms a galaxy cluster called Arp 331.
