450 On Two neiv Sj^ecies of Myonycteris. 



LV. — Preliminary Descriptions of Two neio Species of 

 Myonycteris. By Knud Andersen. 



Myonycteris wroughtoni^ sp. n. 



Diagnosis. — m- about twice the bulk of p^. Skull and 

 teeth heavy. Forearm about 65-67 mm. Hah. Welle 

 District, N.E. Congo. 



Differential characters. — Skull larger and more heavily 

 built than in M. torquata^ '. total length 34 mm., against 

 31-31'8 ; rostrum longer and broader: from front of orbit to 

 tip of nasals 10-5-l0'7, against 9-9-2, lachrymal width (across 

 lower edges of lachrymal foramina) 9-8-10 mm., against 8-8 ; 

 length of combined orbital cavity and temporal fossa, mea- 

 sured on underside of skull from front of glenoid fossa to back 

 of maxillary process of zygomatic arch, lO'T-ll mm., against 

 9-9-8 ; frontal region broader: interorbital breadth 6 mm., 

 against 5-5*2. Cheek-teeth on the whole slightly broader ; 

 m"^ less reduced in size, being about twice the bulk of // (in 

 M. torquata subequal to //), actual length of tooth in two 

 specimens 0*9 mm., against 0-5-0-7 in two M. iorqaata, 

 breadth 0-6-0*7, against 0-4-0-5. — Wings, tibia, and foot 

 conspicuously longer ; forearm 65-67 mm. (57-60-5 in 

 M. torquata), third metacarpal 44*5-45 (36-39), lower leg 

 25-25-5 (22), foot with claws 17-19 (14). Distribution and 

 colour of fur as in the allied species. 



Type, c? ad. (skin and skull). River Likandi, Welle 

 District, 18th April, 1906; Alexander-Gosling Expedition; 

 13. M. 7. 7. 8. 25. Two specimens examined. 



Named in honour of Mr. R. C. Wroughton, who assisted 

 in working out the mammals collected during the Alexander- 

 Gosling Expedition f- 



Myonycteris leptodon, sp. n. 



Diagnosis. — m^ about twice the bulk of p^. Molariforra 

 teeth short and narrow. Forearm about 61-62 mm. 

 hah. Sierra Leone ; Liberia. 



Differential characters. — Skull similar to that of 31. lorough- 

 ioni but rostrum narrower in front (distance between inner 

 bases of canines 3-3 mm., against 3-7-4 in M. wroughtoni
