HEMIDACTYLUS Cuv. 



Hemidactylus loxgickps Cope. 



This species is like the H. coctsei D. B. in its very sparse tuberculation, 

 for this appears in a single line of obtuse distant warts, on each side the lum- 

 bar region only. The thumb has a claw, however, and the tail is surrounded 

 by rings of prominent tubercles. It has fewer tubercles than the H. f r e n a- 

 tus, and diflt'ers further in having a long flat slender muzzle. The width of 

 the head behind the orbits does not measure from the end of the muzzle to 

 the posterior margin of the orbit, while in the H. f r e n a t u s it reaches the 

 rictus of the mouth. Labials 10 — 9; mental projecting behind ; postmentals 

 two pair, the outer considerably smaller, the inner largely in contact. Femo- 

 ral and preanal pores in one series. 



Light reddish-brown, with a pale dark brown bordered ochraceous band 

 from the end of the muzzle to the groin. Dorsal region brown-shaded ; below 

 white. 



Length to vent 47^^ ; to axilla 24^^ ; to ear 13^^.

 No. 478. 



Hemidactylcs hexaspis Cope. 



Tubercles flat, round, sparse, in a row on each side the median vertebral 

 line, and three rows on each side, at a distance from the former. Caudal tu- 

 bercles in three rows on each side. Labials 11 — 8, symphyseal produced be- 

 hind ; postmentals abruptly larger, three on each side, the median pair in 

 contact half their length, the outer diminishing regularly. Femoral and pre- 

 anal pores continuous in the male, both wanting in female. Three internasals ; 

 no tubercles on head or nape. Abdominal scales ovate, rather large. 



Plumbeous above, with numerous pale blotches ; a pale band from end of 

 muzzle to groin, margined with leaden above and below, in the female with 

 blackish ; top of muzzle dark shaded above. 



Length to vent 57^^ ; to axilla 2h" \ to ear 13^^. 



Two specimens from Madagascar. No. 494, Mus. Peabody Academy. 



This species is also related to the H. f r e n a t u s, but differs in the arrange- 

 ment of the dorsal tubercles, and in the chin shields. 



I may note here that the Liurus capen sis [Hemidactylus capensis Smith, 

 Zool. S. Afr.) occurs in the copal of Zanzibar. A specimen over two inches 

 long, enclosed in a block of this substance, is in my possession. Its skeleton 

 and viscera have been dissolved, and form a thick fluid easily visible on 

 moving the specimen. The specimen has been included some time before 

 t^e solidificaiion of the gum, as the gases evolved during decomposition have 

 raised large bladders in two places in the specimen. Another Gecko, pro- 

 bably a Hemidactylus, also occurs in the copal. 



Pentadactylus brcnneus Cope. 



Nostrils surrounded by four small shields and the first labial, the rostral 

 being excluded. The anterior of the scales separated from its fellow by a 

 polj'gonal scale, which is not included in a notch of the rostral. Rostral 

 fissured above. Superior labials eleven, last two minute ; two or three of 

 them longer than high. Distinguishable inferior labials nine; two first much 

 deeper than long. Infralabials not marked, forming some four or five rows 

 of small ovate scales. Scaling of the body coarse. No superciliary spine ; 

 no preanal pores. Free joints of the toes, especially of the thumbs, thick.
