130- CURRENT LITERATURE. 



Judging from the figures we should not have hesitated to place this species in 

 the genus Ralnadvipin or Nilgiria, the author however proposes a new sub-genus for 

 its reception to which the name R'lvanri is given. The malacologist of the future 

 who is bold enough to describe the anatomy of the Indian land mollusca, will have a 

 formidable and perplexing nomenclature to deal with and unravel, to say nothing 

 of the synonyms.

 of Oman, and Arabian Sea, as evidenced mainly through the collections of Mr.

The title sufficiently explains the scope of the present work, which forms a 

 valuable and comprehensive survey of the Mollusca of the Persian Gulf and Arabian 

 Sea. The present part treats of the Cephalopoda, Gastropoda, and Scaphopoda, 

 and of these the authors enumerate 935 species of which 77 are new, contained in 

 171 genera, one of which is new. 



It is impossible here to do more than point out some of the many interesting 

 peculiarities of this fauna. A single species, Aygonauta liians, Soland, represents 

 the Cephalopoda. There are no Amphineura mentioned. Few Patellae, Fissurcllae, 

 or HcUiotis occur. Amongst the Trocliidae many endemic species are found. 

 Natica abounds ; so do the Littoriiiidae, and allied small families, the Ilissoidac 

 being especially interesting ; the Cerithiidac are also plentiful. Mnrcr is not here 

 represented by any of the larger species, the same may be said of Fusus, Lotoriuin, 

 and Purpura. Murcv (Ociiicbra) bomhayauus, Melv. , is interesting as the Indian 

 analogue of M. crislatus, Brocchi, from the Mediterranean. Many Columbellidae, 

 Engiimc, and lllcinulae seem peculiar, as also many Nassac and Milrae, — while the 

 BuUidac are especially interesting. Tcrebra, is represented by 23 small species, 

 mostly endemic. The Leptoconus section of Conus here attains its ma.Kimum de- 

 velopment ; while the Pleurotoinidac are by far the most numerously distributed 

 family. Oliva hardly occurs, and Valuta is absent. Beautiful and peculiar forms 

 of Scalariac, Canccllariae, and Trichotropis are especially noteworthy. 



The Tectibranchia are represented by 41 species of which 5 are new. Two 

 species of Siplwnaria from the coasts of India are peculiar. Among the Scaphopoda, 

 Cadulus is represented by C. culoides,- n. sp , and 0. gadus, Sby. , and 11 species of 

 Dcntalium. 



The authors hope, at no very distant dale, to publish a second part treating of 

 the Pelecypoda.

The new species are P. daut~ciihcrgl, P. bavaiji, P. tenuis, P. fislicri, P. anccyi, 

 and P. pcrslmilis. Coloured figures of all the species are given, in addition to 

 figures of the parietal and palatal armature. Figures of P. cmigrans, MUdff., are 

 also given.
