colu'-iiella, their tiuc position is someuhat doubtful. Nine species 

 have been described, all from the Sandwich Islands. (4) The 

 genus or subgenus Catinella of Pease. These are Si/aiiiecc of 

 aberrant form. Pfeiffer only mentions 2 species. 



The cn'y cthtr genera that are abundant in these Islands are 

 Si.c nea 12, Piija 9, and Helidna 8 species. One species has 

 been referred to Feri/ssacia, a very doubtful identification, the shell 

 is probably an AchatiiicUa. 



5. Australian Region, ^^'e include in this Region, Australia, 

 Tasmania, New Zealand, and the following small islands : Norfolk 

 Island, Kermandec, and the Auckland Islands. 



True Helices exist in this region in large numbers, and of fine 

 forms. Operculates are chiefly reuresented by Piipina, Rcalia 

 and Heliciiia. Pariula is altogether wanting. Taken on the 

 whole the fauna has a much nearer resemblance to that of the 

 Malay Archipelago than to the Polynesian. 



A. Australia. The north east coast is the richest part. Beyond 

 the tropic land-shells are comparitively few, though some have 

 been described even from the interior. Cox's Monograph of 

 Australian Land Shells, published about ten years ago, gives a 

 complete account of all those then known; others have since been 

 described. Vitrina, or more probably Helicarion, is abundant (18 

 species). One species has been referred to Simpulopsis, though 

 this is a very doubtful identification, Sinipiilopsis being an American 

 genus. Nanhice are comparitively few, 20 species. Trochomorpha., 

 on the other hand, has 19 species. One species has been referred 

 to the Madagascan s.g. Ainpelita. The characteristic subgenera

 have spoken under New Caledonia. Dorcasia has 4 s] ecies, Camena 

 5, and Planispira 4; all showing a Malayan affinity. P'lectof/ rpis, 

 an Asiatic genus, is represented by one species. Six species have
