76 TROPIDOLEPIS UNDULATUS. 



On each side of the abdomen is a long green blotch, surrounded with black, 

 which runs to the anterior extremities; and the lighter central portion of the 

 abdomen, meeting the hghter line extended from the inferior surface of the 

 anterior extremities, forms a cross on the thorax. 



The tail is dusky, with several transverse bands of black. 



The anterior extremities are dusky above, with transverse bands of black even 

 to the toes, with a few white spots on their anterior and posterior surface; the 

 under surface is silver-grey. The posterior extremities are coloured hke the 

 anterior, both above and below. 



Dimensions. Length of head, 7 lines; length of body, 3 inches 3 lines; length 

 of tail, 4 inches; total length, 7 inches 8 lines.

 climbing with great facility to the tops of trees, and is hence not taken alive 

 without great difficulty. Its food is insects, especially such as are found under 

 decayed wood. 



Geographical Distribution. The Tropidolcpis undulatus has a very extended 

 geographical range. It is abundant in the forests of New Jersey, and is found 

 even as far north as latitude 43°, whence it reaches the Gulf of Mexico along the 

 Atlantic States; and is also common west of the Alleghany mountains, as I have 

 seen individuals of this species from Mississippi, Louisiana, and Arkansas; and 

 Say observed it at Engineer Cantomnent, on the Missouri river. 



General Remarks. There can be no doubt that this animal was first 

 observed in Carohna by Bosc, who, in his notes furnished to Latreille and
