 extent with ash ; upper jaw presenting several chocolate colored spots upon a 

 lighter ground ; posterior extremities barred with dark brown approaching to 

 black ; abdomen ash colored ; chin and throat chocolate spotted ; under surface 

 of extremities blackish mingled with ash ; when examined with a magnifier 

 the body appears to be blotched all over with dark brown on a much lighter 

 ground. 



JJimendons. Length of head and body 1 inch ; length of head 5^ lines ; breadth 

 5 ; from tip of snout to anterior extremity 5 ; distance between anterior and pos- 

 terior extremities 5 lines ; length of arm 3 lines ; of forearm 2\ ; of hand to ex- 

 tremity of longest finger 3 lines ; of thigh bl lines ; of leg t> lines ; of foot to 

 extremity of longest toe 5.1 lines. 



Habitat. Gaboon. One specimen in Mus. Acad. N. S. presented by Dr. Henry

It measures 1 inch 4 lines in length from the extremity of the snout to the 

 posterior extremity of the body; bead large ; body very slender posteriorly ; the 

 color is of a darker brown than in the adult, and a number of darker blotches 

 may be observed over diil'erent parts of the animal; a characteristic mark, and 

 one which does not appear to have been mentioned in the previous description, 

 consists in the presence of an orange-colored undulating line a short distance 

 above the auus, commencing on the posterior part of the thigh about two lines 

 from the latter ; beneath this line the ground color is more obscure. This line 

 exists also iu the adult specimen, but is of a yellow color.

 DACTYLETHRA, Cuvier. 



There i.s one specimen of Dactylethra, but this differs from the Dacty- 

 lethra of the Cape, and more especially in the presence of a sharp pointed 

 spur projecting from the cuneiform bone, which is not observed iu Dactylethra 

 capensis. 



Dactylethra Mullkri, Peters. 



Sp. Char. Black above, dark brown or chocolate below ; a cutaneous appen- 

 dage beneath each eye; numerous crypts upou the muzzle, chin, and under part 

 of the muzzle ; a series of larger longitudinal glands upon chin ; a sharp pointed 

 spur at base of first toe. 



Dcscj-iption. The head is small, depressed ; the snout rounded ; the eyes pro- 

 minent; the nostrils near the extremity of the snout a line apart, and three- 

 fourths of a line from the anterior border of the eye; the snout is quite smooth 

 above, but covered as far as midway between the eyes, (the posterior border of 

 which is but three lines from its anterior extremity,) with numerous small ele- 

 vated granules or crypts, the under part also, as well as the chin ; a semicircu- 

 lar row of longitudinal glands, nine or ten in number, Avith open mouths, four 

 or five in each longitudinal row upon the chin ; no tongue or palatine teeth ; 

 numerous small teeth in the upper jaw; ejistachian foramen large, broader than 

 long ; body large, subquadrate, about a line broader posteriorly, where, as Du- 

 meril and Hibron observe, it has the appearance of being truncate; perfectly 

 smooth both above and below ; with a ui:ignifier, however, presenting a minutely 

 granular appearance ; no lateral line of pores visible ; anterior extremities small, 

 posterior very large ; fingers free ; fourth finger stoutest, second longest, third
