8 S.TOSTEDTS KILIMANDJARO-MERTT EXPEDITION. 2. 



Length of skull of R. sjostedti about 40 mm. Frontal region of skull between post- 

 orbital processes somewhat convex. Molars not very narrow transversal diameter of 

 first molar 2 mm. and last premolar still thicker. 



This new bat is most nearly related to Rousettus angolensis (BoCAGE) and differs 

 like that one from R. leachi (A. SMITH) == R. collar-is auct., which lived in the same caves, 

 most conspicuously with regard to the structure of the palate. Unlike R. leachi, the new 

 species has only 3 complete palatal elevations and behind those 3 mesially interrupted 

 folds. The presence of only 3 complete palatal elevations was pointed out by BOCAGE 

 as a characteristic for the by him 1898 1 described species angolensis. MATSCHIE 2 used 

 the same characteristic as well for the definition of his new genus Myonycteris, which 

 comprised the species torquata and angolensis. The latter has, however, proved to be 

 a true Rousettus by its cranial characteristics. Te same is also the case with the 

 present new species. As a specific characteristic the number of complete palatal eleva- 

 tions serves very well, and by this among other characteristics the new species is easily 

 separated from another East African bat R. lanosus. From R. angolensis with the same 

 number of complete palatal elevations, R. sjostedti differs in the structure of the palate 

 having only three (instead of four) mesially interrupted posterior palatal folds. This 

 characteristic may, however, be variable as in the type specimen there are rudiments 

 on one side of a fourth divided fold between the second and third. In addition to 

 this there are many differences in dimensions and other exterior characteristics as is 

 proved by the description above. R. angolensis is more hairy, for instance, on the tibia 

 and the interfemoral membrane. The former is said in R. angolensis to be covered 

 en dessus de poils longs et serres>> - - jusqu'a 1' articulation du pied, - 



en dessous jusqu'au premier tiers de la jambe and the latter presque entierement 

 couverte en dessous de poils aussi long et aussi fournis que ceux du dos, while in R. *j<">- 

 stedti both these parts are practically naked. 



The tibia of R. sjostedti is longer than that of R. angolensis but shorter than that 

 of R. lanosus. The latter is easily recognized by its small molars.

Kilimandjaro: 1 ? specimen from Kibonoto, Oct. 1905. 



Small upper premolar entirely missing. Forearm 53 mm. No hairs on front sur- 

 face of sella, which has the posterior connecting process rounded. 



Horseshoe not covering the muzzle laterally. Sella rounded above, constricted 

 below the middle, without any hair on its front and lateral surfaces. Posterior connecting 

 process rounded behind, its upper margin a little concave, higher than sella and covered 

 with long hairs. Lateral margins of lancet rather deeply emarginate so that the tip is 

 almost finger-shaped. 



Ears extending beyond muzzle, when laid forward. Tip pointed. Outer margin 

 concave below the tip. Its greatest width shorter than distance from outer notch to tip.
