7. Philippines. These islands contain the finest assemblage of 

 land shells to be found anywhere, whether regard be had to 

 the number of species or to the beauty of the shells. In 

 consequence of Cuming's explorations, they have been known for 

 a longer period than most other extra-European locahties, but 

 still Semper and others have been able to make considerable ad- 

 ditions to the list. It is a pity tliat no good general work on the 

 Philippine land shells exists ; Semper's is chieily anatomical. The 

 most striking characteristic of this fauna is the genus Cochlostyla, 

 which is here represented by 172 species. These shells were 

 formerly included in Helix and Buiimus, but the fact that several 

 were sometimes placed in the one and sometimes the other genus, 

 seemed to indicate that a new grouping was required, and now the 

 genus Cochlostyla, chiefly distinguished by the hydrophanous 

 epidermis, is pretty generally recognized. 2 1 species of Vitrina 

 are attributed to these Islands ; they almost all probably belong 

 to Helicarion. Naniiia are numerous, including some Very large 

 species of the subgenera Rhysota and Hemiplecta, especially 

 JSI. ovum and maxima. The genus Trochomorpha now becomes 

 abundant (14 species). The Helices are tolerably numerous, and 

 include some subgenera that we have not before met with, and 

 that are characteristic of the Eastern Islands, e.g., Chlorcea 8, 

 Obba 15, Chloritis 2, Planispiia i, Axina 9. The subgenus 

 Corasia (21 species), including many beautiful species, as regi?ia, 

 virgo, ptiella, etc., is by some included in Helix and by some in 

 Cochlostyla. 14 species are referred to Hadra. Amphidromiis 

 exists, but there are only 2 species. One shell has been referred 

 tJ Efidodonta, an Australasian, and i to Stylodon, a Mauritian 

 genus. The shell formerly called Cylindrella Cumingiana is now 

 considered by Dr. Dohrn to be an Ennea. 



We may mention that we had not seen his paper in the 

 Malak. Blaetter when we wrote a short article on Cylindrella for 

 the " Quarterly Journal of Concholog)^" In that article, how-
