placed vertically to the axis of the body, the heels overlap; skin above 

 densely tubercular, except on snout and interorbital space which are 

 nearly smooth; underside of body smooth, of femurs granular. Color (in 

 alcohol) brownish gray above, with dark brown irregular markings which 

 on the back join to form four ill-defined longitudinal bands ; indication 

 of a dark band across the interorbital space ; ground color on top of snout 

 anterior to this band and the outer space between the dorsal bands paler 

 than elsewhere; a dark band from nostrils over lores, through eyes to 

 above tympanum; sides with numerous small white spots; limbs with 

 dusky cross bands and whitish spots on the light spaces; underside white, 

 chin and throat minutely sprinkled with dusky. 



Dimensions. — Tip of snout to vent, 24 millimeters; width of head, 8; 

 nostrils to eye, 2.5; interorbital space, 3; diameter of eye, 2.75; diameter 

 of tympanum, 1.5; fore leg from axilla, 14; hind leg from vent, 34; vent 

 to heel, 19. 



Coloration of living specimens. — Iris golden with black reticulations; 

 ground color above olive clay, dark markings blackish ; aide of face dark 

 with the loreal band blackish and whitish spots on upper lip and under 

 eye; underside whitish, with more or less purplish tinge. 



Variation. — The chief variation is found in the coloration of the alco- 

 holic specimens, many of which are quite pale above with numerous 

 small dusky spots without much indication of the pattern described in 

 the type. A pale canthal stripe is often markedly set off from the dark 

 loreal stripe, as is also a pale cross band in front of the interorbital black 

 band. Younger specimens are often uniformly light brownish gray, and 

 the very youngest, of which I have examined a number not measuring 

 more than 7 mm. in total length, seem always to be without any dusky 

 spots on back. All show more or less definite indications of cross mark- 

 ings on the legs. The skin above is equally tubercular in all the speci- 

 mens, young as well as adult. 



Remarks. — This species in many respects approaches S. leprus in gen- 

 eral proportions and aspect (except coloration) but the head is somewhat 

 narrower, the snout is longer and more pointed, the second finger is 

 shorter and the foot longer. It difiers from all the species described 

 before by its coarsely granular upper surface. 



This interesting novelty, according to information furnished by Mr. 

 Camp, was " found under boxes and boards about buildings in city." A 

 number of very young specimens, 7-8 mm. long, were collected with the 

 adult ones. They show no trace of a tail and it is quite likely, as Dr. 

 Thomas Barbour has suggested to me, that they are hatched fully devel- 

 oped from the egg, as we know to be the case with some of the species of 

 Eleutherodactylus.
