gaps between them ; pereopod 5 as long as pereopod 4, article 2 slender, 

 medially constricted on posterior border with distal half of article 2 

 narrower than proximal half; pleonite 4 with small dorsal hump; 

 peduncle of uropod 2 poorly spiniferous compared with other species. 



HoLOTYPE. — AHF N,o. 6113, female, 10.0 mm. 



TypE-LocALrrY.— Station 7249, 27°36'25" N, 115°56'25'' W, 3705- 

 3745 m, Jan. 4, 1961. 



Materials. — Stations 7228 (male, 8.8 mm) , 7249 (holotype). 



Relationship. — This species resembles V em ana Uzata J. L. Barnard 

 (1964b) more closely than it does F. coiwpressa J. L. Barnard (1964b) 

 because of the shape of pleonal epimeron 3. That of F. compressa is 

 rounded-quadrate at the posteroventral corner. Vemana compressa 

 and F. llzata are the only other known members of the genus, both oc- 

 curing in the Caribbean Sea. Vemana lemuresa differs from F. com- 

 pressa and F. Uzata in the narrower article 2 of pereopod 5 and its 

 posteromedial constriction, and the much better developed, nearly sub- 

 chelate gnathopod 1. Coxa 1 is even more acute anteriorly than that 

 of F. Uzata and coxae 4-7 are much smaller than those of F. compressa. 



The outer lobe of maxilla 1 of F. lemuresa has nine spines and the 

 accessory flagellum resembles that of the other known species. The 

 male is identical to the female except that a dorsolateral ridge sharply 

 defines the dorsal hump of pleonite 4. Undescribed parts are shown in 

 the figures. 



Distribution. — Middle Baja California, 3718-3745 m.
