Miscellaneous. 231 



The exothecium is at first confounded with the other membranes 

 in the homogeneous mass of primordial cellular tissues, and may re- 

 main for a long time, or even always, in an indistinct state ; most 

 commonly, however, it gradually acquires its characters ; its utricles, 

 which rise in papillae, or even in hairs on some parts, sometimes 

 acquire an extraordinary development. The cuticle itself may form 

 a thick crust, which assists in limiting the phenomenon of dehis- 

 cence. 



Lastly, as with the production of the filamentous cells and the 

 destruction of the third membrane, it is at the approach of the 

 dehiscence of the anther that the abnormal development, or even 

 the destruction, of the outer membrane takes place. — Comptes

The present species nearly approaches Pteropus medius in size, 

 and is very easily distinguished from all other species by the two 

 humeral spots, and also by the golden-yellow colour of the abundant 

 woolly hair on the ventral side of the wing-membranes, which appears 

 near the lumbar region, on the humeral membrane, and near the fore- 

 arm almost to its end. 



The ears are about one-half longer than the distance between the 

 eyes and the apex of the muzzle. The upper incisors are of nearly 

 equal size, and stand at equal distances apart ; the lower ones, on the 

 contrary, stand in pairs, and the inner one on each side is scarcely 

 one-third of the size of the outer one, which, however, is much 

 smaller than the upper ones. The upper canines are slender and 

 pointed, furnished with a broad furrow in front, and about one-half 

 longer than the lower ones. The first upper false molar is not larger 

 than the outer lower incisor, it stands near the canine, and is separated 

 by a great space from the second caniniform false molar. The third 

 true molar is small, as also the molars in general, the series of the 

 three true and the hindermost false molar measuring 0*0 11 metre, and 

 the entire dental series to the anterior margin of the upper incisor 

 teeth only 0*020. The anterior lower false molar, which agrees 

 pretty nearly in size with the hindermost lower true molar, stands 

 scarcely the half of its diameter from the canine, but nearly twice its 

 diameter from the following caniniform false molar. The length of
