The Texan form described by Baird and Girard as Relcecetes clarJcii 

 has the following characters. It forms the transition between those 

 with longitudinal stripes as Triseriatus and the irregular spotted Macu- 

 latus from Lake Superior. It presents the usual features in the acute 

 head, entirely granulated body, except on the concealed surfaces (the 

 granulation is quite coarse), nearly free toes, etc. The head is acute 

 and elongated; the snout projecting more than in Maculatus. 



The tympanum is large, about two-thirds the diameter of the orbit. 

 The external nares are very near the tip of the snout, or at about one- 

 third of the distance from snout to orbit ; they are separated by less 

 than one-third the width of the rami. The internal nares are decidedh^ 

 more separated than the external, and distant about one-third the in- 

 terval of the rami. The vomerine teeth are in two very small rounded, 

 depressed patches, having a considerable interval, and in a line with the 

 posterior edge of the inner nares. The tongue is broad, ovate, slightly 

 emarginate behind; thin on the edges. 



The fingers and toes are cylindrical, slenderj and dilated or thick- 

 ened at the tips into rounded, depressed knobs. In the hand the outer 

 finger is longer than the second; the cleft between the second and 

 third is deeper than that of third and fourth, and there is the appear- 

 ance of a very slight basal membrane between them, entirely want- 

 ing between first and second. The outer toe is rather larger than the 

 third ; all the toes are connected by a slight basal web, which, however, 

 scarcely extends beyond the metatarus; two tubercles at base of foot. 

 The tibia is less than half the length of the body ; about half the dis- 

 tance from anus to the eyes. 



Color abov^e brownish -ash, with the back covered by ten to twenty 

 large circular dark blotches, arranged in some specimens in two 

 longitudinal series, with a few smaller intermediate ones ; in another 

 distributed uniformly over the back, separated by considerable inter- 

 vals; a narrow dark line from snout through nostril to the eyes, thence 

 through the tympanum, fading out on the sides of the body posteriorly. 

 A narrow light line along the edge of the jaw to the arm. A few large 

 subquadrate blotches on the upper surface of the limbs. Beneath, 

 yellowish- white, with the gular sac tinged with brown.
