LACEETA MUEALIS IN WESTEEN EUEOPE AND NOETH AEEICA. 361 



collar very slightly serrated. Temporal scales rather large, with quite distinct tympanic 

 and masseteric shields, the latter separated from the parietal by two series of scales. 

 The rostral shield very nearly enters the nostril. 25 scales under the fourth toe. 



In my opinion, Easquinet's lizard does not constitute a definable variety, any more 

 than the lizards on the Glenan Isles in Brittany, and I regard it as almost certain that 

 were any large number of specimens collected some would prove to be absolutely 

 unseparable from the typical form as occurring on the mainland of the Asturias. 



In North-western and Central Spain and in Portugal there occurs a distinct form 

 which has been insufficiently defined by Seoane as 



Var. BOCAGEI, 



in a pamphlet issued in 1885 (antedated 1884) under the title of " Identidad de Lacerta 

 Sckreiieri (Bedriaga) y Lacerta viridis, var. Gadovii (Boulenger) i investigaciones 

 herpetologicas de Galicia." 



" Lacerta muralis, Laur., var. Bocagei, nov. var. Comunisimo en toda Galicia. Esta 

 forma, intermedia entre muralis fusca y muralis pytiusensis, se diferencia de la primera 

 per el dorso que es de color verde, y de la segunda por que los flancos son pardos, 

 ademas de los caracteres que espondre al describirla." 



I here give details of specimens from Galicia, received from the late V. L. Seoane 

 and preserved in the British Museum and in the Lataste Collection, from Madrid, 

 received from the Madrid Museum, and from the Serra de Gerez, collected by 

 Dr. Gadow. Specimens from Pontevedra (Bosca) are in the Lataste Collection.
