THE GENUS ERETMOCARIS 



369 



Eye and stalk about equal, together about one-third length of body. Peduncle of 

 antennule a little shorter than eye. 



Legs I and 2 not chelate, but leg 2 with very long carpus and very short propod. 

 Leg 2 longer than leg i and leg 3 than leg 2; leg 4 shorter than leg 3, slender, with 

 exopod. Leg 5 enormously developed; ischium and merus not distinct; merus and 

 carpus each with terminal spine ; propod flattened and expanded, the distal margin on 

 both sides serrated ; length five times the greatest width. Pleopods small. 



An older specimen diflPers little from description given, but legs i and 2 have rudi- 

 mentary chelae, and the telson has lost the lateral spines, while spine 4 is very much 

 smaller than spine 2. 



Species A. IV (Figs. 42-49) 

 Bermuda. Jan. 1935. 



Length 9-05 mm. 



Rostrum nearly as long as segment i of antennule, with one dorsal tooth. Carapace 

 with dorsal tooth, and supra-orbital, antennal and pterygostomial spines, the two latter 

 very small. In this specimen, which was examined soon after preservation, the lines 

 shown on the carapace were distinctly marked in red. 



Telson 3^ times as long as wide, without lateral spines; apex with 5+5 spines, of 

 which the second is much the longest ; posterior margin protuberant between the two 

 large spines. 



Eyestalk much shorter than eye, together less than one-third length of body. Peduncle 

 of antennule rather short and stout, one-fifth length of body, with pointed stylocerite ; 

 flagella about zl times as long as peduncle, the outer one thickened at the base. 



Antennal scale five times as long as wide, with large terminal spine. Palp of maxillule 

 with three setae, unsegmented. Exopod of maxilla very large and broad anteriorly; 

 endopod unsegmented and without distinct inner lobes; endites well developed. 

 Maxillipede i exopod with eight pairs of distal setae and enlargement at base bearing 

 nine setae; endopod of four segments; coxa large, with long setae; epipod large. 

 Maxillipede 2 ischium and merus, and propod and dactyl fused ; epipod large. Legs i 

 and 2 chelate, carpus of leg 2 long and slender. Leg 3 with propod slightly expanded. 

 Leg 4 propod very much expanded, about twice as long as wide ; exopod present. Leg 5 

 very long; ischium and merus fused and together i| times as long as carpus; propod i| 

 times as long as carpus, and about twice as long as wide ; pleopods large.
