MYOTIS IKONNIKOVI Ognev 



Myotia Ikonmkovi Ognev, Anu. Mus. Zool. Acad. Imp. Sci. St. Petersb., vol. 

 16, 1911 (1912), p. 477 (Evseevka, Piiamur Govt., Siberia). 



/Specimen. — One from Imienpo, Kirin, Manchuria. 



As cranial characters were not given in the original description 

 of this form identification must be tentative; but the dimensions 

 are smaller (forearm 31 mm.) than gj'acllis or any other bat which 

 it might possibly be. It is darker as well as smaller than M. mysta- 

 cinus and its skull is a smaller replica of the latter. 



MYOTIS SOWERBYI A. B. Howell 



Myotis so-werhyi A. B. Howell, Proc. Biol. See. Wash., vol. 39, 1926, p. 138 

 (near Tenpingfu, Fukien, China). 



Specimens. — Fifty-four : 1 from Foochow and the remainder (with 

 the type), including 38 in spirits, from near Yenpingfu, Fukien. 



As indicated in the original description, this bat shows considerable 

 resemblance to M. mystacinus of Europe but differs chiefly in the 

 small size of the lower incisor and large size of the first lower pre- 

 molar. Average measurements of 2 male and 13 female t6potypes 

 are as follows: Length of head and body, 41.3; tail, 38.6; ear, 12.3; 

 forearm, 34.8; thumb, 5.8; shank, 15; foot, 7.9; total length of skull, 

 13.2; palatal length, 5.5; mastoid width, 6.8; and maxillary tooth row, 

 6.7 mm. 



Genus PIPISTRELLUS Kaup 



PIPISTRELLUS TRALATIXroS PUMILOroES (Tomes) 



Scotoj)hUus pumiloides Tomes, Proc. Zool. Soc. London, 1857, p. 51 (China). 



/Speci'?ne7is. — Twenty-three : Shanghai, Kiangsu, 2 ; 70 miles south- 

 west of Yenpingfu, Fukien, 2; Kachek, Hainan, 4; and Yochow, 

 Hunan, 15. 



In determining the south China pipistrelles I was glad to avail 

 myself of the advice of G. M. Allen. He refers those of the traJatitius 

 type to this race and considers that the Hunan material varies to- 

 ward abrmnus. The smaller upper premolar is crowded and not 

 visible from the side. Attention may be called to the error made by 

 J. A. Allen (1906) in recording two species of Myotis from the island 

 of Hainan, for his " Myotis abrmnus,''^ included in his list on Swin- 

 lioes' authority, is clearly a Pipistrellibs. It Avas merely an over- 

 sight, for he compares his P. portetisis with Pipistrellm abramus.
