-109. t. 2G. f. 3, 4, 5), but there are no maxillary bones, and the 

 nasal and frontals are more developed. 



The exterior nostrils are on the upper surface of the margin of 

 the nose, above the first third of the upper lip ; and the inner nostrils 

 are large, and, as in the other Meantia, not on the palate, but on the 

 side of the mouth between the lips and the outer edge, near the 

 hinder part of the series of vomerine teeth, nearly as they are in the 

 genus Axolotl, well figured by M. Bibron (Herpet. t. 95. f. 2 a). 



4. I may observe, that we have specimens both of Necturus macu- 

 latus and N. lateralis in the British Museum, the latter from the 

 Ohio ; and I cannot discover any difference between them, except 

 that the one named N. lateralis has two broad, pale, dorsal streaks, 

 and is about half the size of the other specimens ; and I doubt if 

 these dorsal streaks are not the result of youth, and vanish as the 

 animal increases in size, as is the case with the Siren. 



5. While on these animals, I may observe, that Dr. Garden's 

 specimen of Siren that was originally described by Ellis, which is 

 now in the British Museum, shows a number of lines of mucous 

 pores on the chin and on the head, the latter not being so distinct 

 as the former, and a very distinct series of oblong white spots, 

 forming an interrupted line along the upper part of the sides of 

 the body, and continued to the middle of the sides of the tail ; 

 the spots on the hinder part of the body and tail being larger, more 

 distinct, and closer. These spots evidently represent the lateral 

 lines in Tritons and fish, and I have seen them mentioned in the 

 modern descriptions of the animal.
