Blyth's were from Darjeeling; and the type of Cantor's description was from Cherra Pungee. CYNOPHIS HELENA, Daud.; Gthr. /. c. p. 247. I obtained a fine specimen of this Snake in the same locality with D. forsteni, var. ceylonensis. It measures, body 31" 4'", tail 7" 3'". Ventral shields 244, subcaudals 77 ; anal entire. The fifth and sixth labials enter the orbit; and the posterior angle of the fourth all but touches it; the praeocular touches the vertical. A few spots on the sides of the ventrals, the angles of which along the whole length of the body are ashy brown. The ventrals generally, with the exception of those on the anterior eighth of the body, are minutely mottled with ashy brown. With this exception, this specimen agrees in every other particular with Giinther's description. PTYAS KORROS, Reinw. A young specimen, 13f inches, with about one inch of the tail wanting. Fifteen rows of smooth scales, without any trace of keels or any of the vertebral ones, with a pair of apical grooves. The two large loreal shields have a minute one between, evidently a separated portion of the anterior one. All the other characters agree with this species. V. 187, C. 64 (imperfect). Blackish brown above, with numerous narrow transverse white lines formed by the margins of the scales on the anterior half of the body, dull white below. Hab. Nazeerah, Assam. This museum possesses a specimen of this Snake from Darjeeling ; so that its known range is from Java to the last-mentioned locality. ZAMENIS DIADEMA, Schlegel; Gthr. I. c. p. 252. Seven specimens, of different ages, from Agra, Bhurtpore, and Dholepore, have only twenty-seven rows of scales and from nine to thirteen upper labials. In the majority the praeocular is divided or partially divided into two. The imperfectly divided shields appear to be characteristic of the young. Anterior frontals are larger than the posterior, and separated from the vertical by four shields, the outer of which are generally the largest. Loreals usually three; when a fourth occurs it is very small, and is evidently a separated portion of one of the other three. A ring of small shields surrounding |
