 Knysna. 



" This Bat I found in one ewe only, on the Knysna Heads, 

 and it was there literally in hundreds. It was. a sight to be 

 remembered to see them coming out in practically one solid 

 sheet on a shot being fired inside the cave. 



"I was told that this sp3cies was also to be found at Plettenberg 

 Bay and in the forest, but I was unable to obtain it at either 

 place."— C. H. B. G. 



4. Rhinolophus augur K. And. 



c?. 1045. $.1040,1041,1042,1046. Plettenberg Bay. 

 " I found this species only in one of the many caves examined ; 

 it was difficult to secure, owing to the great height of the roof. 

 It is, however, abundantly common everywhere." — C. H. B. G. 



5. PiPISTRELLUS KUHLII FUSCATUS Thos. 



$. 1027. Knysna. 

 " Knocked down in forest at night." — G. H. B. G.

These specimens seem to represent a southern coast species 

 different from that found in Natal and northwards to Mashona- 

 land. They are of a very dark colour on the back, the head 

 rather paler and greyer, and the hair seems longer than in the 

 more northern form. Their forearms are about 45-46 mm. in 

 length. 



The males are darker than the females, the latter, instead of 

 wholly blackish backs, having brownish backs fringed witli 

 blackish externally at the junction of the membranes with the 

 body. Whether this sexual difference is constant we have hardly 

 enough mateiial to be a.ble to state. 



Temminck's Vespertilio dasyihrix^ was stated to have come 

 from the "interior of Caffraria," which would .seem rather to 

 have brought it into the range of M. nataleiisis ; but as the latter 

 is distinguished by its brown instead of blackish colour, and the 

 t^'pe of dasythrix is described as being " noir mat," a description 

 Dr. Jentink has kindly confirmed, we think the locality — at 

 the best, very vague— should be disregarded, and the Knysna 

 specimens referred to Temminck's species. 



With regard to the size of the skull and teeth, these specimens are 

 all quite uniform, with a greatest skull length of about 155 mm., 

 front of upper canine to back of m^ 6"2, greatest breadth of palate 



* Or " (Vasythrix," as it was misprinted in the original description ("Mon. 

 Mamm. ii. p. 268, 1840).
