238 Mr. E. J. Miers on Malaysian Crustacea. 



Archer, A.M.D., and which is in process of determination by 

 Mr. A. O. Walker, F.L.S. Were it not for its occurrence 

 also at Zanzibar, I should have had little doubt of the distinct- 

 ness of this variety from the Smith ii of Natal. 



Trapezia cymodoce (Herbst). 



A male example from Amboina belongs to this species as 

 I have characterized it (Ann. & Mag. Nat. Hist. ser. 5, ii. 

 p. 408, 1878). 



Neptunus pelagicus (Linn.). 



Celebes, Badjoa (an adult male) ; Borneo, Bandjermasin 

 (a smaller female) . 



Neptunus trituberculatus, Miers. 



An adult male is in the collection, without special indication 

 of locality. 



Neptunus sanguinolentus (Herbst). 

 W. Borneo (a female) ; Bali (another female). 



Scylla serrata (Forskal). 



Bali (a male example) ; W. Borneo (a young male, showing 

 the rudimental condition of the rostral teeth characteristic of 

 the young of this species). 



Podophthalmus vigil (Fabr.). 

 Aroe Islands (an adult male in fine condition). 



Thalamita prymna (Herbst) . 



A male is in the collection, without special indication of 

 locality. 



Thalamita Stimpsoni, A. M. -Edwards. 



New Guinea (an adult female). A smaller individual, 

 apparently not specifically distinct, is in the collection, from 

 Aml^pina, in which the fourth lateral tooth is very nearly as 

 large as the rest. It is very probable that Kossmann is right 

 in uniting many species of this genus that, when fewer 

 materials were available for comparison, were considered 

 distinct. 



Goniosoma annulatum (Fabr.). 



Two females are in the Museum, without definite locality. 

 I am not sure that G. sexdentatum is specifically distinct from
