APPENDIX ON A LEPTOGNATHUS FROM SAN PAOLO. 



Leptognathus garmani, sp. nov. L. catesbeyi Cope, Proceeds. Amer. 

 Philos. Soc, 1884, p. 193, not of Dumeril and Bibron. 



Renewed examination of the specimens on which the above determina- 

 tion was based, shows the determination to have been erroneous. A spe- 

 cies from San Paolo has been named by Dr. Boulenger L. ventrimacu- 

 latus,* but the present snake, although resembling that species, does not 

 belong to it. 



Fifteen rows of scales, the median larger, but not maintaining its char- 

 acter as far as the occipital scuta. One pair of normal geneials, which 

 are short, and are followed by two pairs which are arranged en chevron, 

 the angle directed forwards. The anterior chevron leaves a triangular 

 space between it and the normal geneial, to be filled by a triangular plate 

 on each side. Seven superior labials, the seventh largest, the si.\th next 

 in size, and both longer than high. The fifth supports only the postocu- 

 lar, and the fourth the eye, so that the third only enters it by a corner on 

 one side. Loreal a little longer than high. Oculars 0-2 ; nasals distinct ; 

 temporals 1-1-2. Internasals less than half prefrontals ; the latter wider 

 than long. Frontal wide as long, presenting angles both anteriorly and 

 posteriorly, and about two-thirds as long as the large parietals. 



Color light-brown, covered with numerous wide black cross-bands, 

 which narrow towards the gastrosteges, and are sometimes divided on the 

 middle line, one-half alternating with the other. The centres of the 

 spaces of ground color are darker than the margins, and sometimes con- 

 tain a black spot. Top of head blackish-brown, with a T-shaped mark in 

 lighter brown extending from the occiput to the anterior superciliary 

 region, and a brown cross-bar across the anterior part of the prefrontals. 

 Inferior surfaces yellow, with two irregular series of small brown spots, 

 one on each side of the middle line. The ends of the dorsal black spots 

 involve the ends of the gastrosteges. Gastrosteges 158 ; anal entire ; uro- 

 steges 59. Total length 478 mm. ; of tail 105. 



Sao Joao do Rio Negro ; H. H. Smith. One specimen. The species is 

 •dedicated to the able naturalist of Cambridge, Mr. S. W. Garman.
