their elevation and imperfect development. Nor are its talons either so 

 acute, so curved, or so mobile, as those of the Mucliabha. 



The bones of the fore arm and leg are separate in both : and the wrists 

 and ankles of both contain the same number of bones : so also do the 

 digits :* but in the Catarse there are only 4* metacarpal and metatarsal 

 bones, instead of 5 ; and the bones of the fore arm and of the leg are more 

 slender and have smaller articulating surfaces in Catarse than in Muchahha. 



From the foregoing remarks it is apparent that the whole structure of 

 the limbs down to the talons is in the Muchahha suited to scansion, in the 

 Catarse to running. The few observations which follow will shew that 

 these osteological differences are accompanied by others in the structure 

 of the soft parts. The urinary and generative organs with their append- 

 ages, although in one point essential for classification bearing a resemblance, 

 are widely different in each. Placed on the sheath of the penis anterior to 

 the scrotum there is a secreting organ : but, while in the Catarse it con- 

 sists of a hairy lump, having the size and nearly the shape of a walnut, with 

 a deep cleft in its centre terminating in a cavity which is again subdivided 

 transversely into two hairy depressions, in the Muchahha it is simply a 

 longitudinal naked secreting space wholly exposed to view.f The penis of 

 the former is very small, bony, and pointing to the ground : that of the 

 latter large, without bone, pointing anteriorly, and covered by a strong 

 membrane thickly studded with horny points. The prostate gland of the 



* In respect to the metacarpal, metatarsal and digital bones of Catarse, it would perhaps 

 be more correct to say that there are five bones to the former, and only two to the inner digits ; 

 removing the deficiency from the one part to the other. 



f Dissection proves the secreting organ to consist of two bodies in both animals. But in 

 Catarse the two parts of it are closely and firmly knit together over the penis, whilst in Muchab- 

 6a they are quite separated, and have the penis lying freely between them. The secretion is 

 more musky in Catarse than in Muchabba.
