12 BATRACHIA. 



lateral and nearly terminal. The eyes are prominent, subcircular ; 

 the distance between their anterior rim and the extremity of the 

 snout is a little more than one of their diameter. The cleft of the 

 mouth is uniformly curved, and not undulating as in Anaides higit- 

 bris ; its angles extend almost to a vertical line drawn across the 

 posterior rim of the orbit. The maxillary teeth are very minute, 

 almost invisible to the naked eye. The palatine teeth are small, and 

 disposed upon two open curves, one on each side, extending from the 

 medial line of the palate almost to the jaw bone, leaving the inner 

 nostrils in advance of them. The sphenoid teeth are very minute ; 

 disposed upon a double patch. The tongue is proportionally large, 

 elliptical ; adhering along its medial line, and free on the sides, as also 

 posteriorly. 



The neck is very distinct from the head and body. There is no 

 gular fold. The body itself is subcylindrical ; diminishing anteriorly 

 as well as posteriorly ; it is not plicated or folded laterally, though 

 the specimens exhibit vertical lines corresponding to the ribs. The 

 tail is subcylindrical ; rounded above and below ; a little longer than 

 the body and head together ; very much tapering, and terminating 

 into a point. 



The anterior and posterior limbs are of equal length ; but the 

 latter are stouter, and when bent in an opposite direction, alongside 

 the body, they overlap each other the whole length of the carpus 

 and tarsus, including the toes. The inner toe, in both pair of 

 limbs, is quite small ; in the anterior pair, the third is the longest ; 

 the second is a little shorter than the latter, and the fourth, a little 

 longer than the first or inner one. The longest toe, in the posterior 

 limbs, is the third likewise ; the fourth being nearly equal to it ; 

 whilst the second is a little longer than the fourth, which itself is a 

 little more developed than the first or innermost. 



The skin is perfectly smooth externally ; but, on being examined 

 under the microscope, it exhibits a meshwork of little stellated bodies 

 similar to those of Anaides lugubris, but proportionally larger. 



According to a sketch from life, made by Mr. Drayton, the ground 

 color is milky-white, with crowded dots of reddish-brown. On the 

 specimens preserved in alcohol, however, the body, head, and limbs 

 are of a uniform dark-brown ; lighter beneath. Under a low magni- 

 fying power minute dots may be observed scattered all over the 

 surface.
