withoiit definite teeth ; fixed finger with 2 small teeth, one near the base 

 and the other, slightly larger, about the middle of the inner margin ; on 

 the right cheliped sometimes a third tooth nearer the apex of fixed finger. 



Length of carapace in largest specimen, including rostrum, 17 mm. ; 

 length of abdomen to end of telson, 29 mm. 



Several specimens from Meyer Island and Coral Bay ; others from 

 rock-pools at Sunday Island, collected by Captain Bollons. 



I am unable to identify this species with any descriptions known to 

 me, and therefore describe it provisionally as new ; it may, hoAvever, prove 

 to be identical with some of the species of Axius already described. I am 

 a little uncertain if it is properly placed in Iconaxiopsis, but it seems to 

 agree well with Alcock's description of this genus. 



Petrolisthes lamarckii var. rufescens (Heller).

Several specimens found under stones on Meyer Island ; others from 

 Coral Bay, Sunday Island, collected by Mr. T. Iredale. 



These specimens appear undoubtedly to belong to this widespread and 

 variable species as understood by Borradaile, and, on the whole, they agree 

 pretty closely with the variety rufescens. In the larger specimens the merus 

 of the walking-legs usually bears on the upper margin a series of minute 

 spines, but in the smaller specimens these are hardly distinguishable. Bor- 

 radaile suggests that this variety is possibly a distinct species. 



Pachycheles lifuensis Borradaile. 



Pachycheles lifuensis Borradaile, Willey's Zool. Results, p. 424, 1900 ; Grant 

 and McCulloch, Proc. Linn. Soc. N.S.W., 32, p. 155, pi. 1, figs. 2. 2a, 

 1907. 



Numerous specimens from Coral Bay, Sunday Island, and from Meyer 

 Island. 



These specimens seem undoubtedly the same as those from Norfolk 

 Island examined by Grant and McCulloch, and they appear to have been 

 rightly referred to Pachycheles lifuensis, originally described from Lifu, 

 Royalty Islands. Mr. Borradaile describes the left cheliped as being the 

 larger, but the series of specimens before me shows that either the right 

 or the left may be the larger. 



Callianassa articulata Rathbun. 



Callianassa articulata Rathbun, Bull. U.S. Fish. Comm. for 1903, p. 892, 

 1906. 



A single specimen from a rock-pool, Sunday Island, collected by Captain 

 Bollons in 1907. 



This agrees well with Miss Rathbun's description of this species from 

 Hawaiian Islands specimens, except that the cornea does not occupy quite 

 so much of the eye-stalk, occupying less than one-half instead of more 

 than one-half. The specimen also is considerably larger than Miss Rath- 

 bun's, the carapace being 12 ram. long and the abdomen 40 mm., while
