Show 1891.] TRANSCASPIAN REPTILES. 629 6. 73 specimens obtained by M. C. Eylandt at Puli Hatun at the confluence of the Geshef-Rud and the Hari-Rud. Received in 1891. TERATOSCINCUS SCINCUS, Schleg. I have now six Transcaspian specimens before me, measuring from 40 to 90 millim. from snout to vent: five from Ashabad (Eylandt and one from Puli Hatun. In one of these specimens (from Asbabad) the scales on the back of the head are larger than on the snout, as described by Boettger, the five others having them smaller than on the snout or at any rate not larger. Nostril between the rostral and four nasals; upper nasals in contact with each other behind the rostral in the specimens from Ashabad, separated by one scale in the one from Puli Hatun. Mental as long as broad or longer. 29 to 31 scales round the middle of the body. Head variegated with dark brown ; nape and back with black cross-bands, the anterior of which are crescentic. CROSSOBAMON EVERSMANNI, Wiegm. This Gecko must be one of the commonest Sand-Lizards in Transcaspia, as every collection made in that district contains numerous specimens. The number of prseanal pores varies from six to nine. GYMNODACTYLUS CASPIUS, Eichw. The Museum now possesses the following series of specimens, in all of which I have counted the longitudinal rows of ventral scales (V.) and (in the males) the femoro-prseanal pores (P.):- V.
