Coluber rosaceus, sp. nov. (Plate xxxvi, Fig. 3.) 



Head oval, dist met from body. Rostral plate visible from above; 

 internasala much shorter than prefrontals. Frontal wider than in allied 

 -pities, as broad as it is long, with straight anterior border. Parietals 

 longer than muzzle from frontal plate. Loreal longer thau high; pre- 

 ocular not reaching frontal, but separated by the very narrow anterior 

 extremity of the superciliary. Temporals 2-3-4, the posterior small. 

 Scales of body smooth, rather wide, the first row a little wider than the 

 second. Postgeneials smaller than pregeneials, but distinct from gular 

 scales. Gastrosteges bent up at the sides. Tail probably long, as in 

 C. quadrivittatus, but the end is lost. The urosteges remaining num- 

 ber 47. 



The ground color of the superior surfaces, in the rather fresh alco- 

 holic specimen, is buff, each scale with a dusky baud within and par- 

 allel to the border, surrounding a buff center. This band may be broken 

 up into spots. The greater part of the superior surfaces is occupied by 

 a series of vermilion-tinted pink spots, which extend across the back 

 to within two and three scales of the gastrosteges, thus covering from 

 twenty-one to twenty-three scales transversely. Their length covers 

 six scales everywhere, though as the scales are more elongate anteri- 

 orly the spots are also more elongate. The lateral spots of other species 

 are here represented by pale tracts continuous with the light yellow of 

 the belly, which alternate with the dorsal spots, extending to an apex 

 on the fourth and fifth row. In other words, the cross-bands of dusky 

 ground color bifurcate on the flanks, and terminate at the extremities 

 of the gastrosteges. Below their termini, at the lateral angle of the gas- 

 trosteges, is a short longitudinal black bar or spot crossing one or two 

 gastrosteges. This represents the black line which occupies a similar 

 position in the C. guttatus. At the anterior and posterior parts of the 

 body the dorsal spots have short serrate anterior aud posterior borders. 

 Four indistinct longitudinal bands traverse the length of the body, on 

 the fourth and fifth and tenth and eleventh rows of scales on each side. 

 The inferior band is very obscure, especially anteriorly, and both are 

 less distinct on the true skin than on the epidermis. 



The head is of a reddish color above; below yellowish. A faint 

 dusky band extends across the temporal region and parts of the super- 

 ciliary and frontal plates, meeting a corresponding one of the opposite 

 side. This represents the space between the bands of the C. guttatus, 

 which consists in this species of ground color only. Superior and pos- 

 terior margin of the upper labials obscurely dusky.
