The Texan form (h'seribed by IJaird and (rirard as Ilelaretcs vlarkii 

 has the foHowiii;;- chaiiieters. It forms tlie transition between tliose 

 with h)n{;itudiMal striiu-s as Triseriatns and tlie inejjniar spotted Maen- 

 hitnsfrom Lake Superior. It presents the usual features in the aeuto 

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

 granulation is quite coarse), lu-arly free toes, etc. The head is acute 

 and elongated; the snout projecting more than in Macuilatus. 



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 fiom snout to orbit; they are separated l>y less 

 than one thir<l the width of the rami. The internal nares are deci<le«lly 

 more separated than the external, ami 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 iniu-r nares. The tongue is broad, ovate, slightly 

 emarginate beliiiul; thin on the edges. 



The lingers and toes are cylindrical, slenderj aird dilated or thick- 

 ened at the tips into rounded, deitressed km)bs. In the hand the outer 

 finger is longer than the second; the cleft between the second an»l 

 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 betwe^Mi lirst 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. 

 Th(^ tibia is less than half tlie length of the body ; about half the dis- 

 tance from anus to the eyes. 



Color above bntwnish ash, with the back covered by ten to twenty 

 large circular dark blotches, arranged in some specimens in two 

 longitudinal series, wiMi 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 lino 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.
