EAST AFRICAN REPTILES AND AMPHIBIANS 45 



some geckos in East Africa from the descriptions without comparative 

 material. 



In 1868 Cope described a gecko from Manila, Philippine Islands, as 

 H. longiceps. It was later found to be a synonym of H. frenatus 

 Dum^ril and Bibron. 



In 1873 Bocage described E. longicephalus as a West African mem- 

 ber of the genus. 



In 1885 Boulenger, presumably on the grounds of the similarity of 

 longicephalus to longiceps, proposed H. hocagii for Boc age's gecko. 

 H. longicephalus must stand, however, as the name is not preoccupied. 



In 1897 Tornier described H. hocagei for a gecko, whose scalation 

 he says is very similar to that of H. squamulatus, which he described 

 on page 10 of the same work. A few months later he renamed his 

 H. hocagei as H. werneri on account of the preoccupation by the name 

 Boulenger had proposed. 



In 1902 Mocquard became aware of Tornier's duplication of the 

 name hocagii, but presumably had not seen the later correction, for he 

 agam renamed H. hocagei Tornier, this time as H. tornieri Mocquard. 



In 1913 Nieden relegated squamulatus to the synonymy of tropi- 

 dolepis Mocquard, a species which is apparently closely related to 

 H. longicephalus Bocage. 



I must confess that when naming my specimens in East Africa with 

 inadequate Hterature I got confused and since 1923 have been misap- 

 plying H. squamulatus Tornier to adults of E. werneri Tornier and 

 E. ciiernii Boulenger to some ver}^ juvenile E, werneri. This means 

 that E. citernii is still unknown from Tanganyika Territory, though 

 my 1920 record of its occurrence at Nairobi, Kenya Colony is quite 

 correct. The two geckos from Morogoro, which were identified as 

 E. squamulatus Tornier in 1^20, were correctly identified, but should 

 be called E. tropidolepis Mocquard if Nieden is correct in considering 

 that the two species should be united. 



There are seven specimens of E. werneri werneri in the Museum of 

 Comparative Zoology; they are from the following localities: 



No. 18251, from Itende, Dodoma district, Tanganyika Territory. 

 No. 18252, from Mbala, Dodoma district, Tanganyilca Territory. 

 No. 23041, from Dodoma, Dodoma district, Tanganyika Territory. 

 Nos. 18496-8, from Kilosa, Kilosa district, Tanganyika Territory. 

 No. 21933, from Kibwezi, Kenya Colony. 



The last-mentioned Jizard was received from the Berlin Museum 

 identified as E. werneri. The first, as well as the two in the National 

 Collection, were those previously considered citernii and are too small 

 to be of much use. Four of the above series agree with the type in 

 having 7 upper labials, and seven are in agreement in possessing 

 6 lower labials; the full range, however, is 6 to 8 upper and 6 or 7 lower. 

 Two of the three males have 11 praeanal pores like the type; the third
