men. adult male. Otf Talaur isl. South of Mindanao. Philipp. (Stat, 

 214). 500 fms., a rather small, male specimen. 



Remarks. This new species is allied to the two preceeding. 

 forming, together with them, a distinct section of the genus, charac- 

 terised by the form of the antennal scale, and the peculiar develop- 

 ment of the epimeral spines of the last segment, It is however 

 readily distinguished from both of them, by the long. and slender 

 spines. issuing from the infero-posterior angles of the carapax, and 

 by the strong development of the antennal and branchiostegal 

 spines. 



6. Gnathophausia Willemoesii n. sp. 



Carapax. with the lateral keels, distinct. although not very 

 prominent, the dorsal keel strongly marked, and uninterrupted in 

 the middle, posteriorly produced in a rather large spine. reaching 

 the end of the 2nd postabdominal segment. Bostrum a little shorter 

 than the carapax. rather narrow. and sharply pointed. with few 

 denticles. Infero-posterior angles of the carapax rounded off. Supra- 

 orbital spine strongly developed. acute; antennal spine also well 

 marked, branchiostegal spine obsolete. 5 anterior postabdominal 

 segments dorsally keeled, and provided with small spines in the 

 middle of the posterior margin. The posterior lobe of the epi- 

 mera much more prominent than the anterior. and lanceolate. 

 Epimeral spines of the last segment not connected on the ventral 

 face. Eyes rather small, claviform. with short pedicles. Antennal 

 scale of the form usual in the Caridea. scarcely twice the leugth 

 of the antennular peduncle, broadly ovate. the outer margin 

 straight, and produced in a strong anteriorly directecl spine, the 

 inner boldly curved. and denselj* setose. apex forming a rounded 

 lobe. only very sKghtly surpassing the spine on the outer edge: a 

 very oblique suture runs from the base of the apical spine, across 

 the scale. dividing it into two unequal parts. Telson rather large, 

 lingviform. the lateral margins evenly arched, and densely armed 

 with unequal denticles; the terminal si«ines curved. and finely den-
