THE BATRACHIa" OF NORTH AMERICA. 357 



There are three styles of coloration prevalent among individuals of 

 this variety, viz : That which prevails amoug more northern specimens, 

 but which occur as far south as San Diego, where longitudinal bands 

 are wanting or broken into irregular small spots, and where the inter- 

 ocular triangle is often wanting. Second, where the general color is 

 darker, with three broad dorsal bands or the spots into which they are 

 resolved. The largest specimens are of this type 5 numbers having 

 been brought from Fort Tejon and a few from northward. Third, rep- 

 resented by a large female specimen from Monterey, Cal., is without 

 markings above, but the borders of the exterior color of tibia?, the sides, 

 and the pectoral region are closely brown spotted; in all the others the 

 under surface are immaculate. The tints of this style seem to be more 

 delicate, and it has a more hyline aspect than some of the others. 



Head small, rather pointed, but broader than long. Tympanum 

 small, nearly half the diameter of tlie eye. Eyes not very prominent ; 

 a slight fold of skin above the tympanum. A very prominent one 

 across the breast. Skin above finely pustulated with larger scattered 

 tubercles, not so close as in H. versicolor. Tibia about half the length 

 of the body. The gular sac is largely developed. 



Disks on extremities large; the largest equaling the tympanum. 

 The hand considerably longer than the fore-arm ; outer finger longer 

 than the second; a slight web at base. Tibia half the length of body. 

 Outer toe a little longer than the third. Membrane extending from 

 disk of outer toe to middle of the third joint (from the tip) of the fourth 

 or longest; from the third articulation (from tip) of the fourth toe 

 obliquely to the disk of the third toe ; from the third articulation of 

 the third toe to the disk of the second ; from the second articulation of 

 the second toe to penultimate articulation of the first. Thus the mem- 

 brane is nearly w^anting along the inner side of three terminal joints of 

 the third and fourth toes and the two terminals of the second, while on 

 the outside it extends nearly or quite to the disks of the second and third 

 and to the penultimate articulation of the first and fourth. A promi- 

 nent tubercle at base of inner toe and a smaller one opposite on the 

 sole. Expansion of sacral apophyses not very great. The heel of the 

 hind leg extended reaches to the anterior border of the orbit. 



In a very large specimen the general color above is a greenish-ash 

 (in some a dark olive) and blotched with darker. Tiiere is a conspic- 

 uous subequilaterally triangular patch between the eyes, extended 

 acutely backwards for a short distance. The back is variously blotched ; 

 the most conspicuous of the blotches are considerably elongated, and 

 arranged one or two in a line on each side of the back in a line with 

 the eyes and parallel; the middle of the back and the extreme sides 

 of the body are sparsely provided with smaller, usually subcircular, 

 sometimes elongated blotches. There is a distinct and rather broad 

 dark line from the snout through the nostrils to the eye and a wider 

 vitta from the eye, involving the whole tympanum, to a little past the
