of Xew Caledonia, the frontal teeth are much smaller and less pro- 

 minent than in either Hilgendorf's figure of his 0. speciosus or in 

 the two specimens I have before me. As, however, Prof. A. Milne- 

 Edwards had evidently a larger series for examination, and unites 

 0. guttatus and 0. speciosus, I do not venture to regard the two forms 

 as distinct species. 



Mr. Haswell records 0. gnttatus from Port Denison and Port 

 Curtis. 



This species has evidently a wide Oriental range, having been 

 found in the Red Sea, at Zanzibar, Mauritius, Batavia, Torres 

 Straits, and Xew Caledonia. 



66. Neptunus pelagicus (Linn.). 



Of this very common Oriental species two males are in tho first 

 collection from Port Curtis, 7 fms. (Xo. 88), and a male from Prince 

 of \Yales Channel, 3-4 fms., in the second collection. Specimens 

 from the same locality are in the collection of the British Museum, 

 obtained during the voyage of H .M.S. ' Rattlesnake ' by Mr. Mac- 

 gillivrav, and also from the following Australian localities: — Port 

 Jackson (J. Macgillivray) : Sydney (It. Schutte); Swan River (J. B. 

 Jala) ; Shark Bay, W. Australia (F. M. Bayner, H.M.S. ' Herald') ; 

 also from Xew Zealand (Sowerby). 



Besides the above, there are specimens in the Museum collection 

 from the Red Sea (Major J. Barton, Major MacDonald) ; Gulf of 

 Suez (R. MacAndreiv) ; Zanzibar (Dr. Kirk) ; Pondicherry, Indian 

 Ocean (Gen. HardwicJce) ; Penang (Dr. Cantor); Borneo (Bleel-er's 

 coll.); Celebes, Badjoa, &c. (Dr. Bheher's coll.); Timor Laut (H. 0. 

 Forbes); Philippine Islands, Zebu (Cuming); Shanghai, Cheefoo 

 (Swinhoe); Japan (Mas. Ley dm); Honolulu (H.M.S. ' Challenger''); 

 New Caledonia (Macgillivray) ; also others, without special indica- 

 tion of locality, from the collections of the • Herald,' ' Rattlesnake,' 

 and ' Samarang.' 



The Neptunus armatus, A. Milne-Edwards, from Shark Bay, W. 

 Australia*, of which the types, from the collection of H.M.S. 

 ' Herald,' are in the British-Museum collection, is not referred to in 

 Haswell's Catalogue. The specimens are of small size and probably 

 not fully grown. Both carapace and limbs are slightly pubescent. 

 The carapace is relatively somewhat narrower, and the antero-lateral 

 teeth broader and less distant one from another than in N. pela- 

 gicas of about the same size, which otherwise this species very 

 closely resembles. 



67. Neptunus ( Amphitrite) hastatoides (Fabricius). 



Three examples are in Dr. Coppiuger's second collection from 

 Friday Island, Torres Straits, 10 fms. (Xo. 153), and a series of
