angle of the carapace is much smaller and directed forwards and not 

 obliquely outwards at an angle of about 45°. 5. The cervical groove 

 is bounded posteriorly by a small spine ; in M. stijlirostris both groove 

 and spine are very inconspicuous. 6. The merus of the cheliped has 

 two rows of spines on its upper surface, one on the inner the other on 

 the outer margin. 7. All the joints of the 2nd, 3rd and 4th thoracic 

 legs are hairy. 8. The ridges bounding the transverse furrows of the 

 2nd-4th abdominal terga are spinulous not ctenate. 



Colours in life were the same as those of M. stylirostris ; milky 

 orange dorsally, white ventrally, corneae yellow. 



The length of the largest specimen, an egg-laden female, from tip 

 of rostrum to end of telson is 50 millims. 



Station 197 ; 406 fms., 2 egg-laden females and one male. There 

 is also in the Indian Museum an ovigerous female from 30 miles W. of 

 Middle Andaman Island, depth 480-500 fms. 



41. Munidopsis, sp. 



One small specimen, 9 millim. in total length, resembling M. 

 margarita, Faxon, more closely than any other described species was 

 obtained at Station 201 ; 320-296.

The single specimen obtained this year is a male. The chelipeds 

 are unequal, the larger measuring 56 while the smaller measures 49 

 millims. The palm of the larger cheliped is 16"75 millims. and the 

 fingers 6 millims. in length. From tip of rostrum to end of telson is 

 25'5 millims.

Galacantha, a. Milne-Edwards. 

 43. Galacantha trachynotiis, n. sp. 



This species is closely allied to G. uivestigatoris, Ale. and And.^ 

 bella, Hend., and rostrata, A. M. E. 



From the first it differs in the following points : 1. The carapace 

 is covered with short sharp spiniform tubercles the tips of which are 

 bent forwards. Anteriorly these tubercles are somewhat sparsely 

 scattered but posteriorly they are more densely crowded together. 2. 

 Slightly in front of the pair of gastric spinules is a small median
