SCIENTIFIC RESULTS FROM THE MAMMAL SURVEY. 19 



Shull : — Coiidylo-incisiv e length, 27 : basilar length, 23; zygo- 

 matic breadth, 13'5 ; nasal, 12 ; diastema, 8 ; upper molar series, 5. 



Habitat : — Karwar, Kanara District. 



Tyije:— Old female. B.M. No. 12-10-16-3. Presented to the 

 National Collection by the Bombay Natural History Societ3^ 



It is unfortunate that there is no liistor}^ of these two specimens, 

 but it is to be hoped that a series, properly measured in the flesh, 

 will new soon be obtained. 



The second specimen, though showing the mamma3 quite plain- 

 ly, is much younger and smaller, but though the combined head and 

 body measurement is only 75 mm. and that of the skull less than 

 23 mm. the hindfoot is the same size as in the type specimen. 



The specific name refers to its size, which is conspicuously 

 greater than that oi i~)hilliim and surhha, and in which it equals 

 platijtlirix, hitherto the giant of the Geniis. 



^. — Generic classification of the Indian Murine. 



In the 20 years since Blanford published his Key at page 401 of 

 the "Mammalia," great additions have been made to the knowledge 

 of the Indian Murinae, a result the credit for which belongs largely 

 to the Bombay Natural History Societj.^ Since 1891 four Genera, 

 not recognized by Blanford, have been revived, and no less than 

 seven new ones have been established. 



We recognize that any Key drawn up now will almost certainly 

 require to be amended as the Survey progresses ; but we have found 

 that for our own convenience some Key, based on our present 

 knowledge, was necessary ; and we believe it will have a certain 

 value, even though it be only provisional, in enabling Members 

 interested to follow the results of the Survey intelligently. 



We do not claim to have made any special investigations for 

 the purposes of this Key, but have accepted the data recorded 

 by Blanford, when such were available and suitable for our 

 purpose. 



" Mus chiro]:.us," an aberrant species referred to b}^ Blanford 

 in his Key, seems, from the description recorded, to fit into the 

 Genus Hceroinys Thos. fA.M.N.H., p. 207., 1911). We have, 

 therefore, included that genus in our Key to represent it. " M2is 

 erythrotis," known only from a single immature specimen, appears 

 to us generically indeterminable, and we have left it out of con- 

 sideration. 



The following is the Key : — 



I. — Tubercles on anterior lower molar in 3 



longitudinal series; coat silky; mamnvjb 



2—2=8 .' TIAPALOMYS. 



II. — Tubercles on anterior lower molar in 2 

 longitudinal series.
