;CRUSTACEA. 229of New Caledonia, the frontal teeth are much smaller and less prominentthan in either Hilgendorf's figure of his 0. speciosus or inthe two specimens I have before me. As, however, Prof. A. Milne-Edwards had evidently a larger series for examination, and unites0. (juttatus and 0. speciosus, I do not venture to regard the two formsas distinct species.Mr. Haswell records 0. guttatus from Port Denison and PortCurtis,This species has evidently a wide Oriental range, having beenfound in the Red Sea, at Zanzibar, Mauritius, Batavia, TorresStraits, and New Caledonia.66. Neptunus pelagicus (Linn.).Of this very common Oriental species two males are in the firstcollection from Port Curtis, 7 fms. (No. 83\ and a male from Princeof Wales Channel, 3-4 fms., in the second collection. Specimensfrom the same locality are in the collection of the British Museum,obtained during the voyage of H.M.S. Battlesnake ' ' by Mr. Macgillivray,and also from the following Australian localities:—PortJackson (J. Macgillivray) ; Sj'dney (^R. Schutte); Swan River (./. B.Juices) ; Shark Bay, W. Australia {F. 21. Ecti/ner, H.M.S. ' Herald')also from New Zealand (Sowerby).Besides .the above, there are specimens in the Museum collectionfrom the Red Sea (Major J. Burton, Major MacDonald) ; Gulf ofSuez {R. MacAndreiv) ; Zanzibar (Dr. Kirl:) ; Pondicherry, IndianOcean (G^(^/i. Hardiuiclce) ; Penang (Z)/-. Cantor); Borneo (Bleeder'scoll.); Celebes, Badjoa, &c.

Challenger');'New Caledonia (Macgillivray) ; also others, without special indicationof localit}', from the collections of the • Herald,' Rattlesnake,''and Saraarang.''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 inHaswell's Catalogue. The specimens are of small size and probablynot fully grown. Both carapace and limbs are slightly pubescent.The carapace is relatively somewhat narrower, and the antero-lateralteeth broader and less distant one from another than in N. 2J£^cigicusof about the same size, which otherwise this species veryclosely resembles.67. Neptunus (Ampliitrite) hastatoides (Fahricius).Three examples are in Dr. Coppiiiger's second collection fromFriday Island, Torres Straits, 10 fms, (No. 153), and a series of* Arch, du Mas. tl'Ilist.
