400 Bibliographical Notice. 



The above measurements and description were taken from a 

 fresh specimen. 



The molar pattern is as follows : — 



Upper I. 5 spaces, 3 external and 3 internal angles.

This vole, which I have named after Mr. W. T. Blanford, 

 has the molar teeth somewhat like those of Arvicola Roylei; 

 the differences in this respect could only be made intelligible 

 with the aid of figures. The colour and proportions, how- 

 ever, of A. Royhi and A. Blanfordi are widely different. 

 The Gilgit vole is quite distinct from the lately described 

 A. Stracheyi.

The authorities of the Geological Survey of India have worthily 

 opened a new series of their valuable ' Palseontologia Indica ' with 

 an excellent description by Prof. Duncan of the remains of Corals 

 and Alcyonarians from the Upper Cretaceous and Tertiary rocks of 

 Sind. Altogether Dr. Duncan describes and figures 136 species of 

 true corals, the majority of which are pedunculated forms with a 

 well-developed epitheca, and by their characters and relationships 

 indicate the existence of a shallow sea in which the deposits con- 

 taining them were accumulated. This applies even to the corals 

 from the Upper Cretaceous formation, in which no production of 

 reefs or of coral limestone can be traced ; and it is not until we come 

 to the uppermost coralliferous series that we meet wif h massive corals 

 forming reefs and producing a sort of saccharoid limestone. 



Dr. Duncan's researches fully confirm the most recent stratigra- 

 phical results arrived at by the Indian Geological Surveyors. The 

 olive shales immediately underlying the Deccan trap have been re- 

 garded as Cretaceous, although it must be confessed that the palse- 

 ontological evidence available for the determination of their strati- 

 graphical position is not the most satisfactory in the world. The 

 principal fossil, Cardita Beaumonti, is indeed nearly allied to Euro- 

 pean Neocomian and Gault species ; and one Nautilus is said to be
