minute black spots ; telson and uropodites show a blue-black 

 colouration irregular in its distribution. 



Habitat — S.-E. coast of iVrabia, no fathoms. 



Munidopsis spinihirsuta , sp. nov. 



The length of the carapace is ver^^ slightly greater than the 

 breadth. 



The rostrum, which is less than half the length of the cara- 

 pace, curves upwards especially towards the tip, is carinate and 

 bears an obscurely serrated lateral margin. The entire upper 

 surface and lateral margins of the carapace are covered with large 

 pointed spines which curve forwards ; these spines are arranged 

 with some approach to symmetry ; they are most numerous over 

 the gastric regions ; they all bear long hairs. 



There are six spines on the posterior border of the carapace. 

 The upper surfaces of the first three abdominal segments bear 

 hairy spines. 



The eyes are colourless, egg-shaped, and one-third the length 

 of the rostrum ; they are surmounted by a flat, curved, hirsute 

 spine. 



There is a small spine on the anterior border of the carapace 

 between the eye and the second antenna forming the boundary of 

 an orbit. 



The chelipeds are nearly equal and are about as long as the 

 entire body in the male (female unknown). The merus and carpus 

 are covered with spines ; there is a row of small spinules on the 

 inner border of the propodite ; the fingers are shorter than the 

 palm. From the second to the fourth thoracic leg, the mero-, 

 carpo-, and propodite are covered with small spines on their upper 

 surfaces ; the dactylus in these appendages is half the length of 

 the propodite. There are no epipodites on the chelipeds or any of the 

 walking legs. The basal joint of the peduncle of the second antenna 

 has an external and an internal spine of equa size. The flagellum 

 is about the same length as the body. 



Three small males ; largest i^ inch from telson to rostrum. 



Colour — Pinkish yellow. 



Habitat — Off S.-E. coast of Arabia ; 492 fathoms.
