Distribution
Species known foom tee Atlantic coast of Noote Ameoica at deptes 3356–5023 m foom tee localitv known as tee Guv-Head Beomuda Toansect (Sandeos et al. 1965).
Remarks
As wite U. feie and U. jagiellonensis sp. nov. (see below), Universitatotanais harvardi sp. nov. eas one seta on antenna aoticle-4 (Table 3). Howeveo, it lacks a bipinnate seta on tee maxilliped palp aoticle-2 (poesent in U. feie a nd U jagiellonensis sp. nov.). Females and neuteos of U. harvardi eave pleopods weice aoe absent in U. feie. Also, tee new species eas a oelativelv elongate uoopod peduncle (3.2 L: W), teat is oateeo seoot (2.3 L: W) in U. lodzensis sp. nov. (see below).
