 Mus. XXXVI, 1909, p. 92).

 Mus. XXXVI, 1909, p. 92). 



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

0,95 mm. long hilarulus de Man 



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

 laterally. 

 b x Posterior margin of 6 th abdominal somite unarmed.

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



1) Coutière's description of this species does not quite accord with his figures. The lateral spine of the basicerite should be 

 as long as the stylocerite, but in the figures 7a and ia x it appears much shorter; the terminal spine of the scaphocerite should usually 

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