middle of the first joint of the antennular peduucle. The carapcace 

 IS short and unarmed. The first joint of the peduncle of the first 

 antenna is longer than the second and third together, the second 

 and third joints subequal. The inner and outer fiagella are sub- 

 equal and reach well beyond the fringe of the antennal scales. The 

 scale of the second antenua is longer than the peduncle of the firsc. 



The third maxilliped reaches the end of the first joint of the 

 antennular peduncle. 



The first leg exceeds the antennal scale by the hand and the 

 last half of the wrist. The second legs are equal. The merus 

 almost reaches the end of the antennal scale, and is armed distally 

 with a spine at the lower and outer angle. The wrist is short and 

 broad, and the hand longer than the carapace and fairly stout. 

 The fingers are barely half the length of the palm, and the immov- 

 able finger has on the inner side a large swelling, indented by a 

 notch, into which fits the single small tooth on the movable finger. 

 The last three pairs are subequal, the third pair reaching the 

 wrist of the second. 



The exopodite of the uropod is slightly longer than the endo- 

 podite, and both are considerably longer than the telson. The 

 latter is armed at the end with six spines, of which the two 

 outermost are the smallest and the intermediate pair the longest. 



The length of the single specimen is 19 mm. 



Coralliocaris brevirostris is allied to O. macroplitlialma (H. M.- 

 Edw.), but may be distinguished from it by the following features : — 



(1) The rostrum reaches only the middle of the first joint of 



the antennulary peduncle. In C. macrophthalma it reaches 

 the beginning of the last joint. 



(2) The inner flagellum of the first antenna is longer than in 



C. macrophthalma. 



(3) The shape of the fingers of the second chela is different in 



the two species.
