240 Mr. M. A. C. Hinton on 



full account of ibis collection will be publisbed later, but 

 meanwhile it is deemed advisable to publish descriptions of 

 the following three new species : — 



Mimetillus thomasi^ sp. n. 



Type. — An adult female, collected at N'dola on Oct. 4, 

 1919 ; original number 481. 



This interesting bat, represented by a single specimen, is 

 distinguished from its West-African relative, M. moloneyi^ 

 chiefly by its larger size, duller colour, and still flatter skull. 



General outward appearance and all the essential ciiaracters 

 of the genus as in moloneyi. Size larger, the forearm mea- 

 suring 31 instead of 27-29 mm. Third digit of wing relatively 

 a little longer, its total length equalling 165 % (instead of 

 146-159 °/q) of the length of the forearm. Fur on back 

 slightly longer. General colour, above and below, dark 

 brown, deepening almost to black on head, dull, lacking both 

 the gloss and the deep chestnut tinge seen in moloneyi. 



Skull considerably larger (condyle to canine 14*1, instead 

 of 13 mm.), with the characteristic depression and flattening 

 of the brain-case even more pronounced than in moloneyi ; 

 interorbital region relatively broader. Dentition without 

 especial peculiarities. 



External measurements (taken in flesh by collector). — Head and body 

 56 mm. ; tail 38 ; hind foot 7'5 ; ear 13. 



Measiirements of wing (made on skin). — Forearm 31 ; third digit, total 

 length 51, its metacarpal and phalanges 1 and 2 being respectively 32'5, 

 9, and 9'5; fifth digit 36, its metacarpal 29'5. Revilliod's index of 

 width 49. 



Skull. — Extreme length 14'6 ; condyle to canine 14'1 ; canine to in? 5'2 ; 

 ■width of brain-case in mastoid region 9*5 ; median occipital depth 4*7 ; 

 interorbital breadth 5'3 ; breadth across preorbital swellings 8 ; width 

 across outer borders of vv'-iir' 7*8. 



Mimetillus moloneyi was originally described from Lagos 

 by Mr. Thomas. Many specimens were collected subse- 

 quently in Fernando Po; and we have lately received an 

 example from Sierra Leone, collected by Mr^ Willoughby 

 P. Lowe. Hitherto no representative of the genus has been 

 found inland or away from the West-African coast. Captain 

 Shortridge's discovery in Rhodesia is therefore of considerable 

 interest. I have great pleasure in naming the second species 

 of this genus in honour of Mr. Oldfield Thomas, to whom I 

 am indebted in so many ways. 



Kerivoula lucia, sp. n. 



Type. — An adult male collected at N'dola on Sept. 26, 

 1919; original number 472. No other .s[)ecinien seen.
