upon the Diphuiniatlnacea, the Fufinaceq, and the various genera 

 with sutural tubes, such as Alyavus, Opisthoporus, etc. Helicina 

 also first occurs in any numbers in this Province, though it is not 

 so rich as in the Australasian and Pak^otropical Provnices. 



I. India. Very much has been done in this - Region since 

 Woodward's time. Blanford, Beddome and Godwin Austen de- 

 serve special mention, and Hanley and Theobald have published 

 the " Conchologia Indica,"' wliich, though it contains no descrip- 

 tions, and sometimes leaves something to be desired in the 

 execution of the plates, has at least the merit of giving, for the 

 first time, an illustrated catalogue of all the Indian moUusca, 

 Vitrlna has 12, Succinea 10 species. There are 2 species of the 

 curious genus Lit/iotis, separated from Succinea. N'aiiina includes 

 26 species oi Alacrcchlamys, 11 oi Xesta, 13 oi Ariophanfa, besides 

 many others not yet referred to subgenera. There are 6 species 

 of the curious subgenus Plectopylis. Arionta has i species, 

 Fruticicola i, Plcctotropis 2, Eurystoma i, Trackia 5, Planispira i, 

 CoiJla 5, Oxytes i. The peculiar genus Boysia occur here. 

 Streptaxis has 4 species, and E/iiiea, though more African than 

 Ind an, 6. We come for the first time on Amphidromus (2 sp.), 

 and Ceotrochus i. There are 46 species of Buliiniuus and 5 of 

 CyL iJrus, the latter from the N.AV. portion of the region, in the

 operculate genera : Cychtus 2 species, Mychopoma. 2, CyatJioponia 

 21, Spiraculum 3, Pterocyclos 6, Alycceus 53, Opisthostoma 5, 

 Diplommatina 29, Nicida 6, Scabrina i, Cyclophorus 29, Lagocheilus
