Brachyura. 

 Paramithrax peronii, M. -Edwards. Miers, Cat. N.Z. Crust., p. 5 ; 

 Index Faunaa N.Z., p. 247. 



Several specimens from Channel Island, 25 fathoms, and one 

 from 30 fathoms, appear to belong to this species, but they are 

 very small, the largest having the carapace not more than 

 15 mm. long. 



Pinnotheres pisum, Linnaeus. Miers, Cat. N.Z. Crust., p. 48; 



Index Faunae N.Z., p. 250. 



One small male specimen from Channel Island, Hauraki 

 Gulf, 30 fathoms, appears to agree well with the description. 

 As is frequently the case with males, this specimen was found 

 free and not in a bivalve shell. 



It is perhaps worthy of note that Heller's " Novara " speci- 

 mens, which he identified with the P. pisum of Europe, were 

 from Auckland, found in Mytilus. 



Ebalia laevis, Bell. Miers, Cat. N.Z. Crust., p. 56; Index 

 Faunae N.Z., p. 251. 



Three specimens from Channel Island, 25 fathoms. I have 

 also two specimens dredged off the Poor Knights Islands in 

 60 fathoms by Captain Bollons early in 1905. 



Through the kindness of Mr. F. E. Grant I have been able 

 to compare this species with specimens of E. tuberculosa (Milne- 

 Edwards) taken off Sydney at the depth of 300 fathoms ; from 

 these E. Icevis may be distinguished by the smoother carapace, 

 and by having the posterior margin produced so as to give the 

 appearance of three obtuse teeth. Mr. G. M. Thomson has 

 recorded E. tuberculosa from Dusky Sound, 40 fathoms. It was 

 taken by the " Challenger " at station 167, about a hundred and 

 fifty miles west of New Plymouth, in 150 fathoms.* 



Anomura. 



Lyreidus tridentatus, De Haan. Haswell, Cat. Aust. Crust., 

 p. 144 ; and Henderson, " Challenger," Anomura, p. 33. 

 One specimen was taken outside Great Barrier Island in 

 120 fathoms. This agrees well with the description given by 

 Haswell. The prominent dorsal elevations on the 3rd and 4th 

 abdominal segments are present as described by Henderson, 

 except that the one on the 3rd is almost acute, though much 

 smaller than the one on the 4th. 



The species was originally described from Japan, and was taken 

 by the "Challenger" off Port Jackson and also near the Fiji 

 Islands, but it has not been previously recorded from New Zealand.
