THE BATRACHIA of NORTH AMERICA. 151 



pressed and narrowed in section below. No prominent glandular ag- 

 glomerations or i)ores. Only three phalanges in the fourth toe. 



Form of head peculiar. It is very broad, with straight converging 

 maxillary outlines and truncate muzzle; upper surface much narrowed 

 on muzzle; loreal regions plane, very oblique; can thus rostralis not 

 marked. Maxillary outline obliquely spread at and behind orbits, 

 where it is exceeded by the projecting margin of the mandible. Ante- 

 riorly, and at the end of the muzzle, it projects considerably beyond man- 

 dible. Muzzle truncate in profile; a slight emargination at middle of 

 premaxillary border, and a groove on each side of it on inferior pro- 

 jecting face of lip. Nares terminal, some distance above the angulation 

 of the lip, continued below in a groove, which bifurcates near lip mar- 

 gin ; the posterior line extending a short distance, the anterior to the 

 median emargination separating the anterior from the inferior plane of 

 the muzzle. E^^e large, not very prominent; its anterior canthus well 

 in front of middle of jaw, and separated one diameter from nostril and 

 1.5 from the other eye. 



No fold across from angle to angle of mandible, but the gular, paro- 

 toid, and postorbital grooves well marked. Costal grooves indistinct; 

 ]3. Skin everywhere very smooth. 



Tail longer than head and body by the length of the mouth. Width 

 at curves of mandible 4.6 times in length to groin. Extremities slen- 

 der and long; when pressed to the sides the fingers extend to the heel. 

 Length of whole fore limb 2.75 times in length to groin. Inner finger 

 very suiall, half the length of the fourth; third longer than second. 

 Sole narrow ; longer than longest toes. Inner toe less than half the 

 fifth; third a trifle longer than fourth; second much longer than fifth. 

 Lower leg .75 thigh to groin. 



Patches of parasphenoidal teeth, two in contact anteriorly, well 

 separated from palatines. All the teeth minute, numerous, acute 

 cylindro conic. Tongue with rather straight lateral and posterior out- 

 lines. 



Color throughout pitchy black, fading into bright red orange below ; 

 limbs orange, a blackish cross band below the knee. A large red- 

 orange spot on each parotoid region, and four smaller, irregular, similar 

 spots on the body to base of tail on each side of and near the vertebral 

 line. A pair of orange spots at base of tail and a distant series on the 

 upper face of the tail. 



Besides the type, a specimen of this species was obtained at Cape St. 

 Lucas, in Lower California, and I have seen one from near San Diego, at 

 the northern end of that peninsula. As the typical specimen was 

 found at Fort Tejon, Cal., the range of the species is extensive.
