broader than the rest and bifid, and four below ; the carpus with 

 two sinuous or entire crests, separated by a deep groove ; the 

 propodos smooth, slightly dilated, its digital prolongation and 

 the mobile dactylos each with a rounded tooth at their base, and 

 meeting only near their apices, where they are armed with a row 

 of about half a dozen small teeth. Chelipedes of the female 

 differing from those of the male in having the propodos smaller, 

 the digits less arched and without a tooth at the base. First 

 pair of ambulatory legs longer than the rest, as long as the 

 carapace and rostrum ; last pair a little more than three-fourths 

 of the length of the first ; all four pairs covered with hooked 

 hairs and with a spine at the end of their merus-joint. Carapace 

 ornamented with bunches of hooked hairs. Total length Hlths 

 inch ; breadth from tip to tip of anterior branchial spines nearly 

 an inch.

This species belongs to the section of the genus including 

 CMorinus acantJtonotus of Adams and "White, C. longispina of De 

 Haan, C. aculeatus of Milne-Edwards and Paramithrax halimoides, 

 Miers, from all of which it is distinguished by the shape and 

 arrangement of the spines on the carapace. 



Tiarinia elegans, n. s. 



Carapace elongate-triangular. Surface pitted, especially on 

 the branchial and cardiac regions ; gastric regions with several 

 tubercles, the largest situated in the middle line near the posterior 

 boundary of the region, laterally compressed, subacute ; cardiac 

 region with a prominent conical elevation ; branchial regions 

 each with two conical prominences, with a small tubercle in front 

 of them placed in an oblique line. Eostrum forming about one- 

 third of the entire length, formed of two slender cornua which 

 are contiguous to near the apex, where each curves outwards and 

 ends in an acute point. Upper orbital margin not prominent. 

 Merus of chelipedes punctate, with a few tubercles above and
