established, the Matrix of Laurenti. We are therefore restricted to six- 

 species in our search for the type of the genus Coluber. They received 

 generic names at the following dates : 



C. melanocephala ; Taut ilia B. & G., 1S53. 



G. assculapii; Coluber Giinther, 1858. 



('. can us; Pseudaspis Cope, 1864. 



C. mycterizans ; Passerita Gray, 1825. 



C cyaneus; unindentified. 



C earinatus} Herpetodyas Boie, 1826. 

 Giinther in L858 selected the G. cesculapii as the type of Coluber, and 

 to this species that generic name must be applied. 



Mr. Garman, of Cambridge, has followed Dumeril in using the name 

 Coluber foi the C. constrictor Linn. The way in which this conclusion 

 has been reached is as follows: 



The first author whom we have to consider is Fitzinger, whose Xeue 

 Classification der Reptilien appeared in June, 1826, in Vienna. Sev- 

 enty-one species of Coluber are enumerated in this work (p. 57), of 

 which only twenty-two are of Linmeau origin, and to these we must 

 therefore confine our attention. In the following list of them the names 

 of the genera to which these species were successively referred is given, 

 and the date of each:

The latest date only can he considered in this connection, since the 

 names of genera are retained in accordance with the priority of date of 

 each. The latest date at which species of this restricted division Col- 

 uber are referred to other genera is L853. In that year four of them 

 were referred to genera distinct from Coluber, and of these genera three 

 were newly established. These three are Baseanium B. & G., Drom-
