548 MR. O. THOMAS ON MAMMALS FROM NYASSALAND. [NoV. 1, 



of muscles of jaw is exceptionally prominent, I think — much more so 

 than is usually the case. This animal killed a donkey (full-grown) 

 by attacking it in the flank and disembowelling it. The head and 

 neck did not have a single claw-mark on them. This is a most 

 exceptional case, and I do not think I ever heard before of a Leopard 

 killing its prey otherwise than by springing on the head and neck. 



" Another most unusual occurrence in this case was that the Leo- 

 pard returned to the carcass and was shot dead on the third night, 

 after having been wounded on the chest the second night with a 

 charge of small shot, which was afterwards found under its skin." — 

 A. Whyte. 



The basal length of the skull of the old male is 207 mm., and 

 its breadth 148 mm. The length of the cub's skull is 87, and of 

 its long mp' 19 mm. 



2. HyjEna crocuta, Erxl. 



a. Ad. skull. 2. Milanji. .5/11/91. 

 h. Imm. sk. and skull. Milanji. .5/11/91. 



a. "2 ft. 10 in. in height at shoulder and 150 lbs. in weight. 

 Mangy and sparsely covered with short hair ; colours dull. Shot 

 over carcass of donkey killed by Leopard two days previously." 



b. " Three parts grown Spotted Hyaena, shot near same carcass. 

 Same species as a, but with fine long hair, and colours well defined, 

 looked quite a different species but proved only to differ in being 

 younger and in finer felt." — A. W. 



Skull a is 241 mm. in basal length, and 179 in breadth. 



3. Petrodromxis tetradactylus, Peters. 



a. Zomba. 1/9/91. 



b. Zomba. 



c. Ad. al. S • 



4. Vesperus megalurus, Temm. 



a. Ad. sk. Milanji Plain, 4000 ft. 18/12/91. 



b, c. Ad. sks. Zomba. 10/12/91 and 1/2/92. 



d-o. 3 ad. $ and 9 young in al. Forearms of adults 47'3j 

 47'.5, and 48*5 mm. 



This rare species was unrepresented in the Museum collection 

 when the Catalogue of Bats was published, but a single specimen of 

 it procured by Dr. Dobson in the Drakeuberg Range, Natal, was 

 obtained from that gentleman in 1881. 



5. Vesperugo nanus, Peters. 

 a. Ad. al. S . 



6. SciURUS MXJTABiLis, Peters. 



a, b. Milanji Plateau, 6000 ft. 27/10 and 25/11/91. 



These two specimens are of considerable interest and value as 

 helping to clear up the confusion which surrounds the relationship 

 of S. shirensis, Gray ^, to S. mutabilis.
