126 THE VOYAGE OF H.M.S. CHALLENGER. 



(which lies behind the supraorbital). In other respects this variety cannot be distin- 

 guished from the typical form of Munida suhrugosa ; indeed, on examining a series of the 

 latter nearly all the above-mentioned spinules can be made out in different specimens, 

 though I have failed to see any in which so many were present at the same time. 



Habitat— ^isiiion 162, off East Moncceur Island, Bass Strait; depth, 38 to 40 

 fathoms ; bottom, sand. Several specimens, the majority of which are females ; the 

 body of the largest measures only 25 mm. in length. 



Munida stimpsoni, A. Milne-Edwards (PI. XIV. fig. 1). 



Munida Stimpsoni, A. Milne-Edwards, Bull. Mus. Comp. Zool., vol. viii. No. 1, p. 47, 1880. 



Habitat. — Station 122, off Pernambuco ; depth, 350 fathoms; bottom, red mud. 

 A male specimen measuring as follows : — Length of body 36 mm., of rostrum 5 "6 mm., 

 of chelipede 73 mm. 



The chelipedes are extremely long and slender, somewhat scaly, and armed with 

 spines ; the propodus is more than twice the length of the carpus, and the fingers are 

 long, slender, and straight. The eyes are slightly compressed. The rostrum is not 

 twice the length of the supraorbital spines, and all three are slender. The gastric 

 region of the carapace is armed with two pairs of spinules placed posterior to the supra- 

 orbitals, and a single spinule is present on its lateral aspect ; the cardiac area is slightly 

 elevated and bears a median and two lateral spines, these last being situated on the 

 confines of the branchial regions. The lateral margin of the carapace is but slightly 

 spinose, though the first or postorbital spine is well developed ; two spinules are placed 

 near the middle of the posterior margin, which is marked by a line of considerable width. 

 The hairs on the carapace are slightly iridescent. The merus of the external maxillipedes 

 possesses a single spine on its inner margin. The ambulatory limbs are slender and 

 slightly flattened. The second, third, and fourth abdominal segments are armed with 

 spinules on the anterior margin. 



This species appears to be abundant in moderately deep water throughout the West 

 Indies. It was taken by the " Blake " at no less than twenty stations, in depths 

 varying from 62 to 1105 fathoms.

Habitat. — Station 122, oflp Pernambuco; depth, 350 fathoms; bottom, red mud. 

 Four males and three females, one of the latter with ova. The body of the largest 

 specimen (a male) measures 70 mm. in length, and the chelipede 83 mm.
