icus Bibron, and Haldea B. & G. Now Dunieril, who published the 

 prodroinous of his classification of the serpents in 1853, expressly retains 

 the name Coluber for the C. constrictor of Linureus, type of Bascanium. 

 But as the C. constrictor is not included in the Oppelian genus Coluber 

 of 1811, it can not be considered here at all. 



Shortly after the appearance of the work of Fitzinger, Boie furnished 

 a synopsis of his systematic work on Reptiles to the Bulletin des Sci- 

 ences Naturelles, edited by Ferussac, 1826, ix, page 237. He gives a list 

 of thirty-five species of the genus Coluber, of which only six are Lin- 

 naean. Of these but three appear in the list from Fitzinger, given above. 

 These are C. cyaneus, G. Jiippocrepis, and C. constrictor, thus restricting 

 the name to the C. constrictor. 



Soon after, however, Boie gave a list of the genera of snakes, with a 

 typical species for each, in the Isis von Oken, 1827, page 9S2. Here he 

 cites the C. el aphis (Elaphis qu a t err a diatus Gem., Dum. & Bibr.) of Eu- 

 rope as the type, and adds " u. v. a," which means, und viel andere — 

 species belonging to the genus. What these other species are, may be 

 derived from a perusal of a previous paper by Boie in the same vol- 

 ume, page 209, where he describes three closely allied srjecies from Ja- 

 pan, the whole belonging to the genus Elaphis of Dumeril and Bibron, 

 and one of them (Coluber conspicillatus), being a member of the genus 

 Coluber of Giinther. Dr. Giinther has regarded this reference as an 

 indication of the meaning of Boie in his use of the name Coluber, and 

 this determination must stand on the ground of previous determination 

 by Oppel. 



Pitycphis melanoleucus Holbr. Distributed throughout the State. 



Spilotes corais erebennus Cope. Volusia. 



Cyclophis aestivus L. Generally distributed. 



Bascanium constrictor Linn. Volusia and Key West. 



Bascanium flagelliforme Catesby. Throughout the State. Georgiana. 



Heterodon platyrhinus Latr. Generally distributed. 



Heterodon simus. From the northern and western parts of the State. 



Storeria occipitomaculata Holbr. Volusia. 



Allied to this genus is Tropidoclonium Cope, which has the anal shield 

 entire. 1 have referred to this genus the Begina lirtlandh of Kenni- 

 cott. This species, however, has a divided anal plate, and must be 

 therefore assigned to a distinct genus. This I call Clonophis, with the 

 following characters : Teeth equal ; anal plate divided ; nasal plate 

 partly divided, loreal present ; scales keeled. Head not distinct from 

 body. 



Allied to this form is the Virginia inornata of Garman, from Texas. 

 It agrees with Tropidoclonium except in the absence of preocular plate, 

 the loreal extending to the orbit. It must be referred to a distinct ge- 

 nus, which I call Amphiardis, with the following characters : Teeth 

 equal; anal plate entire: nasals two; internasals two; no preocular, 

 its place taken by the loreal ; scales keeled. Head not distinct.
