72 Mr. R. I. Pocock on 



Ventrals 146; anal divided; subcaudals 28 + «, possibly 

 40. Posterior maxillary tooth strong and separated from the 

 preceding by an interspace. 



Upper parts brown, with four rather indistinct blackish 

 lines, the outer along the fourth and the inner along the 

 seventh series of scales ; upper labials yellowish, marbled 

 with blackish like the throat ; lower parts greyish, nearly 

 black. 



The length of the single specimen is 18 inches, of which 

 the somewhat mutilated tail measures two. 



This species seems to be allied to Liophis quinquelineatus 

 (Ann. & Mag. Nat. Hist. 1881, vol. vii. p. 359), of which 

 the type has been lost. It differs, however, by its somewhat 

 larger eye, fewer series of scales, and different coloration 

 of the head. 



X. — R'port upon the Crustacea collected by P. W. Bassett- 

 Smitti, Esq., Surgeon R.N., during the Survey of the 

 Macclesfield and Tizard Banks, in the China Sea, by 

 H.M.S. 'Rambler,' Commander W. U.Moore. By R. I. 

 Pocock. 



This collection of Crustacea is composed principally of 

 Brachyurous forms of small size. Seventeen species have 

 been identified, and of these three are now described for the 

 first time. This percentage of new species from seas so well 

 known is distinctly good. The chief interest centres in the 

 Maioid forms, two of them being new to science and the rest 

 noticeable in other respects. 



In addition to the species here enumerated several small 

 specimens of a species of Alpheus were taken ; but the iden- 

 tification of these has not been attempted, on account of their 

 immaturity and imperfect condition. 



1. Gonodactylus chiragra (Fabr.). 



One small specimen in 3 feet of water at the north-east 

 extremity of the reef. 



2. Galathea australiensis, Stimpson.

Two specimens without chelipedes in 32 fathoms of water
