Miscellaneous. Ill 



species formed at Port Dorey by M. Raffray and now in the Paris 

 Museum. 



Five sixths of M. Raffray's collection consist of marine Gastero- 

 pods ; a few terrestrial Pulmonata and fluviatile forms and eighteen 

 Bivalves complete the collection. 



Among the marine shells nearly all the great Lamarckian genera 

 are represented. The genera Conus, 3Iitra, Turbinella, and Stromhus 

 are the richest ; but there are also a good many species of Cerithiim, 

 Parjiura, Riciiiula , Nassa, Cohanhella, Triton, Ranella, Murex, Ovala, 

 Cypnea, TrocJius, and Turbo. On the whole these shells show 

 clearly that the Papuan marine molluscan fauna is closely related to 

 the great fauna of the Indo-Pacific region, and especially to that of 

 the Moluccas. 



The terrestrial molluscan fauna of jN'ew Guinea has a more special 

 character and appears to be much more related to that of the islands 

 of Oceania, the Solomon and Admiralty Islands. The forms and the 

 types are the same, although the species are different. This view is 

 confirmed by the few terrestrial species in M. RafFray's collection. 

 Nearly all the Helices must be placed in the groups Pajyuina, Geo- 

 trochus, Cloritis, and Albersia, and Leptopoma predominates among 

 the Operculata. 



In this collection there are two interesting forms which the 

 author regards as quite new. One of them forms the type of a new 

 genus, which the author names Perieria, after Professor Perier, 

 and characterizes as follows : — 



Genus Pebieria. 



Testa sinistrorsa, fusiformis, multispira, apice truncata : apertura 



elliptiea ; peristoma continuum, expansum ; axis sinuosus, basi 



contortus et columellam truncatam atque subdentatam simulana. 



This genus approaches Clausilia ; but the want of folds in the 



columella, the false tooth at its base, and the truncation of the 



spire serve to separate the two genera. The species is 



Perieria clansiliceformis, Tapp.-Can. 



P. testa anguste fusiformi, crassiuscula, satis nitida, fusco-cornea, 

 dorse (an fortuite?) albescente, peristomate paUidiore. Spira 

 turrita, supra medium attenuata, apice decollata. Anfractus 7^, 

 regulariter creseentes, convexo-planulati, oblique et confertim 

 per longitudinem inciso-striati, sutura impressa, suhcrenulata 

 sejuncti ; ultimus major, basi subovatus. Apertura pyriformis, 

 supeme angustata, peristomate incrassato continue. Alt. 0-065, 

 lat. 0-012 m. 



A new species of Ileliv is described as follows : — 



Helix Raffrayi, Tapp.-Can. 



H. testa latissime et prof undo umbilicata, orbiculato-pyramidata, 

 acute carinata, sub lente crebre per longitudinem striata, dia-
