Before passing on to the Fishes I offer remarks on a few of these species.

Nostril between two nasals and the suture between rostral and first labial. Lower eyelid scaly. Collar present. Back covered with scales larger than those of the tail, and strongly keeled, the keels forming continuous longitudinal ridges; sides with much smaller scales; ventral scales rather large, imbricate, keeled, the keels again forming continuous series. Fingers and toes slender, with a double series of smooth, very small scutes beneath, Femoral pores; no inguinal pores. Tail long, cylindrical.

General aspect of a Tachydromus.

The scutes on the upper side of the head show longitudinal ridges either along the middle or concentric with their margins. The anterior nasal meets its fellow in the median line behind the rostral. Anterior frontal longer than broad; an unpaired small scute between the posterior frontals. Vertical bell-shaped twice as long as broad; a pair of anterior occipitals,
