Dytopa, Illiger. M. Temminck is of opinion that Moloum, Nycti- 

 nomiu, and Cketromekt are identical with Dyiopc*. The following is 

 the character of the teeth, according to F. Cuvier : two incisors above 

 and four below ; two canines in each jaw ; four molars on each side 

 of the upper jaw ; that is to say, two false and two normal ; ten 

 molars in the lower jaw, namely, four false and six true. Type, 

 It. Stoopt. We proceed to give the definition of Molotmt, Cheiro- 

 mda, and Nyrtinnnna, for the assistance of the student. 



Molouut. Head short ; muzzle swollen. Ears large; earlet external. 

 Interfemoral membrane straight, with a square termination. Tail 

 long, envelo|>ed at its base, and most frequently free at ita extremity.

The geographical distribution of this form is wide : Africa, Asia, 

 and South America possess it : but the species, which are numerous, 

 occur principally in the two last-mentioned localities.

 Size of the Barbastelle of Europe. Fur composed of hair of two 

 colours, blackish-brown above, and ash-brown below. Whiskers at

Cktiromda, Honfield. Two incisors above and two below; the 

 upper one* large, approximate, semiconical, and acute, the lower very 

 mnall and simple. Muzzle conical, sulcated, and with setiferous 

 glandule*. Ears distant, patent, with a short, semicordate, obtuse 

 .lum. Axillary pouch ample ; but the hind foot, according to 

 hr. Horefield, constitute* the chirf distinguishing character. The 

 hind foot, or rather hand, " consists of four fingers, which have the 

 wunc disposition and structure as in other animals of this family, and 

 of a distinct thumb, ementially agreeing with this member in many 

 iju-iilrumana, and in several animal* of the Rixlenlin and Marsnpialtu. 

 It is a complete antagonist to the fingers, enables the animal to take 

 hold of object*, and thus constitute* a perfect hand."

We now come to a numerous and widely distributed family e,,n- 

 taining some of the largest forms of the VmptrtiUimtdct, and subsist-

 fabulous Harpy may have had its origin in some of these enormous 

 bats with their well-developed pectoral uiammce.
