 length by 15"5 mm. in breadth.

Two small and. imperfect specimens, the larger only 15 mm. in length, belong 

 apparently to this common species, though the characteristic " ocelli " are very faintly 

 indicated on the carapace. 



Locality. " Torres Straits."

Two specimens, about 22 mm. in length , are no doubt referable to this common species, 

 though they differ in some slight details from large specimens. In general shape and 

 in the character of the antero-lateral teeth they approach the N. armatus of A. Milne- 

 Edwards [1. c. p. 322, pi. xxxiii. fig. 2), but the external frontal teeth are not in our 

 specimens obtvise, and the spine on the median supra-orbital lobe is indicated, though not 

 so large as in full-grown specimens of N. pelagicus. As Ortmann has pointed out (Zool. 

 Jahrb. Syst. viii. p. 75), it is very doubtful whether N. armatus is a distinct sj)ecies. 

 Milne-Edwards says of it : " Cette espece est de tons les Neptunus connus la plus 

 elargie " ; while Miex"s, referi'ing to the vei*y specimen described by Milne-Edwards, states 

 that " the carapace is relatively somewhat narrower .... than in N. pelagicus of about 

 the same size" (Rep. Voy. 'Alert,' Crust, p. 229), 



Locality. " Fringing reef, Mabuiag."

Neptunus {Achelous) granulatus, Alcock, Journ. Asiatic Soc. Bengal, ixviii. (2) p. 45 (1899). 



A female specimen, 12 mm. long, agrees well with De Haan's figure, except that, as in 

 all young specimens, the lateral spines are more elongated. 

 Locality. " Murray Island."
