times (9) longer than wide Mac-Cullochi Cout. 



(H. COUTIERE, in: Bull. Soc. Philom. Paris, 1908, p. 13 and in: Proc. U.S. Nat. 

 Mus. XXXVI, 1909, p. 92). 



d„_ Carpocerite 3,75 — 3,8-times as long as wide. Palm of large 

 chela with an obtuse tubercle on the anterior margin. Lower 

 spine of basicerite as long as the basal part, upper angle 

 subacute, with no spine. Merus of third legs 4,6 — 5-times as 

 long as wide. Rostrum slender, extending to the 2^^ third 



part of median antennular article gracilirostris de Man 



c^ Terminal spine of scaphocerite shorter than the carpocerite. 

 d^ Palm of large chela with a feeble flattened prominence on 

 the anterior margin. Chela 2,6-times as long as high. Carpo- 

 cerite 3,6-times as long as wide. Stylocerite not longer than 



the lower spine of basicerite Mushaensis Cout. 



(H. COUTIERE, in: Bull. Soc. Philom. Paris, 1908, p. 12 and in: Proc. U.S. Nat. 

 Mus. XXXVI, 1909, p. 92). 



d„ Palm of large chela ending in a small, acute spine, chela 2,82- 



times as long as high. Carpocerite 3, 5-times as long as wide. 



Stylocerite much longer than the lower spine of basicerite. 



Merus of third legs 3,66-times as long as wide. Ova large, 



0,95 mm. long hilarulus de Man 



b.^ Large chela 2,35 — 2, 5-times as long as high, palm unarmed. Carpo- 

 cerite 2,66 — 2, 7 1 -times as long as wide, about as long as the 

 terminal spine of the scaphocerite; upper spine of basicerite 

 strong. Merus of third legs 3,12-times as long as wide. Rostrum 

 shorter than basal antennular article. Eggs producing zoeae . . Latastci Cout. ') 

 (H. COUTIERE, in: Proc. U.S. Nat. Mus. XXXVI, 1909, p. 25, fig. 7). 



Biunguiculatus group. 



«j Movable finger of the small chela tapering, not widened or enlarged 

 laterally. 

 b^ Posterior margin of 6* abdominal somite unarmed. 

 c^ Merus of third legs unarmed. 



d^ Dactylus of small chela without a dorsal brush of hairs. 



l) Coutiere's description of this species does not quite accord witli his figures. The lateral spine of the basicerite should be 

 as long as the stylocerite, but in the figures Ta and 7ff[ it appears much shorter; the terminal spine of the scaphocerite should usually 

 slightly exceed the carpocerite, but in both figures it appears shorter.
