122- Mr. E. J. Miers on the Squillidse. 



penultimate segment is apparently coalescent with the ter- 

 minal, although the line of union is clearly indicated, and is 

 armed with six convex tubercles. The terminal segment is 

 suboblong, with the postero-lateral angles rounded ; its upper 

 surface is armed with three convex rounded tubercles disposed 

 in a triangle ; behind these the upper surface is marked with 

 impressed lines, which reach to the posterior margin ; the 

 posterior margin has a median notch, and is divided by 

 narrow fissures into about six truncated lobes. The styli- 

 form termination of the dactylus of the raptorial limbs is very 

 short and unarmed. The outer of the spines of the basal pro- 

 longation of the uropoda is larger than the inner, and is not 

 armed with a tooth on its inner margin. Length of the 

 typical specimen in the Museum collection (a male) about 

 1\ inch. 



Hab. Swan River, one male ( Coll. Brit. Mm.) ; Sharks' 

 Bay, West Australia, in holes in coral (H.M.S. 'Herald'), 

 two males. 



This species is recorded by Dana from the Fiji Islands, and 

 by Heller from Auckland. Hoffmann, in 'Recherches Faune 

 Madagascar,' Cr. p. 43, cites this species from the Mauritius ; 

 but he may have had specimens of G. Folinii or an allied 

 form. 



Gonodactylus trispinosus, var. jpulcliellus, nov. 



By this name I designate a small male from Ceylon, pre- 

 sented to the Museum by E. W. H. Holdsworth, Esq., which 

 may very probably constitute a distinct species ; but I await 

 the examination of a larger series of specimens before deciding 

 this point. It differs from the typical G. trispt?iosus in the 

 absence of corrugations on the median portion of the fifth 

 postabdominal segment. The median spine of the rostral 

 plate is absent, but may have been broken off close to the 

 base. Length about lj inch. 



Gonodactylus glyptocercus. 



Gonodactylus qlyptocercus, Wood-Mason, Proc. Asiatic Soc. Bengal, 

 p. 232 (1875); Ann. & Mag. Nat. Hist. (ser. 4) xvii. p. 263 (1876). 



This species is only known to me by Mr. Wood-Mason's 

 short notice in the ' Proceedings of the Asiatic Society of 

 Bengal,' according to which it is allied to G. trtspinosus, but 

 has the terminal postabdominal segment ornamented with two 

 oval tubercles, bounded by an impressed invected line, and 

 with a median basal cinquefoil-shaped one, and the two pre- 

 ceding segments symmetrically engraved with fine lines. 



Hab. Nicobars.
