SCIENTIFIC RESULTS FROM THE MAMMAL SURVEY. 609 



Myotis peytoni, Wrought. 



A very distinct species, cliaracterised by its considerable size 

 (forearm 45-46 mm., skull length 17-18) and the crushing in of its 

 middle premolars, both above and below. It shows no approxima- 

 tion to Lauconoe either in foot or skull. 



Myotis m'uricola, Gray. 



Not so common a bat as has been supposed, three out of the four 

 synonyms assigned to it by Blanford being really referable to the 

 mystaGinus group. V. (Fterno'ptefus) lohipes, Peters, from Arakan 

 is alone correctly placed under muricola. 



The skull is broader and more solidly built than in the mystacinus 

 group, and the teeth, especially the canines, are heavier, and the 

 posterior of the two small premolars is more crowded inwards: 

 There is a narrow post-calcarial lobule. 



Bats referable to muricola occur from Kashmir through the 

 Himalayas and down farther India to Borneo and Java. 



Myotis amboinensis , Peters's ^'Vespertilioadvfirsusyav. amhoine^isis'''^ 

 not mentioned in Dobson's Catalogue, is a larger ally of M. muri- 

 cola found in Celebes, Burn, Amboina and Ceram. 



Myotis mystacinus group. 



To this group are referable quite a number of the names which 

 have been applied to the smaller Indian members of Myotis. Thus 

 siligorensis, Tomes, darjelingensis, Tomes, caliginosus, Tomes, hlan- 

 fordi, Dobs., niioalensis, Dobs., and moupinensis, M. Edw., all seem 

 to be assignable to this group. 



How many Indian species there are in it I am not at present 

 able to determine, but all may be distinguished from the European 

 mystacinus by the deeper and more sharply defined notch on the out- 

 side of the ear. There appear to be at least two distinguishable forms, 

 one with low brain case and the canines of normal size, about as in 

 mystacinus, and the other with a high crown and the canines much 

 reduced, especially below. For the first the earliest name is cali- 

 ginosus (syn. hlanfordi and perhaps nipalensis'), and for the second 

 siligorensis (syn. darjelingensis), both represented by their types in 

 the British Museum. 



Bats of this group have as yet only been found along the moun- 

 tainous regions of N. India, not in the South, nor in Ceylon. 



II. — Leuconoe. 



The genus Leiiconoe is richer in Indian species than has been 

 supposed, and I find that five different forms may be recognised. 

 Blanford includes four species, but one of these \ i^> the European
