OCYPODE KUHLII. 251 



I ouly fouud two specimens of this beautiful , apparently 

 rare species , a nearly adult male , collected by Kuhl and 

 van Hasselt on the shores of the island of Java, and 

 another fine adult male , also fi'om the Indian Archipelago , 

 the former specimen being the type of de Haan's short 

 description. 



In its outward appearance , the cephalothorax very well 

 resembles that of Ocyp. arenaria Catesby from the West- 

 Indies , being broader than long , the breadth of the upper 

 surface being in proportion to the length as 4 : 3. Like 

 in Ocyp. arenaria Catesby and in Ocyp. cordimana Latr., 

 the acute external orbital angles project beyond the roun- 

 ded prominence of the supraorbital margin, but are direc- 

 ted outioard and not inward as takes place in the two quo- 

 ted species. The epibranchial angle projects more outward 

 than the orbital angle and the granulated lateral margins 

 are therefore convexly arcuated , though being rather con- 

 cave immediately behind the triangular external orbital 

 angles. The front is much deflexed and arcuated anteri- 

 orly, with a minute median triangular incision at its an- 

 terior margin. The upper surface of the carapace is much 

 convex longitudinally and granulated , more coarsely on the 

 lateral portions than in the middle. Suborbital margin mi- 

 nutely denticulated , internal suborbital tooth denticulate. 

 Convex pterygostomian regions coarsely granulated. Exter- 

 nal surface of the external maxilli pedes a little granulated. 

 Peduncles of the eyes ivitJiout any trace of terminal prolon- 

 gation. External surface of the sternum and of the male abdo- 

 men minutely granulated , the first segment of the sternum 

 (between the anterior legs) armed with two granulated rid- 

 ges on each side. Anterior legs very unequal in size; arms 

 as in Oci^p. cordimana Latr., upper margin rounded and 

 transversely rugose , internal and external margins of the 

 smooth under surface armed with dentiform tubercules. 

 External rounded margin of the carpopodite granular, in- 

 ternal angle denticulate. Hands much compressed and more 

 dongate than in Ocyp. cordimana Latr., the upper margin
