beyond its centre it has a projecting lobe which fits into a 

 correspondino^ dc])rcssion in the free finger. ^J'lie free finger 

 IS finely dentate in its distal half or so ; its proximal half 

 forms a projection, with its free margin coarsely dentate, 

 which fits into a depression at the basal end of the fixed 

 finger. There is no epipodite on any of the thoracic legs. 



The ambulatory legs are long ; the first pair are longer 

 than the fully extended body. The merus of the first three 

 pairs has a row of spines almost thronghout the whole extent 

 of its anterior border, and this is continued along the ante- 

 rior border of the carpus as a row of spines, and not merely 

 as a terminal spine ; their dactylus is hardly or only very 

 slightly more than half the length of the propodite. 



Three egg-laden females and one male were taken in the 

 trawl at Sta. 310, Bay of Bengal, 960 fathoms. The male 

 unfortunately had lost its chclipeds. The largest female 

 gives the following measurements :— 



mm. 

 Length of fally extefnded body, iucluding rostrum . . 30-6 



„ chelipeds 39 



„ first pair of ambulatory logs 31 '8 



This species is very closely allied to M. Goodridgn, from 

 which it differs mainly in having no spines or spinules on the 

 cardiac region; chclipeds not very iniequal, both of them 

 much longer than ihc fully extended body, and both edges of 

 the outer sui'face of the palm spinose ; legs more spinose, 

 the carpus having a row of two or more spines, and not 

 merely a terminal spine on its anterior border ; the lateral 

 border of the carapace with three spines and two spinules 

 instead of two spines and one spinule. 



This new species has been figured for the next issue of

One male specimen (length of body, including rostrum, 

 43 mm.; length of chclipeds 24^ mm.) was caught at Sta. 

 32G, Bay of Bengal, 1100 fathoms. It presented the following 

 peculiarities : — Carapace and abdomen tomentose ; lateral
