158 Mr. Gr. A. Boulenger on the Varieties 



(A. parilis, Pasc. 1882) is the <J of A. indigaceus, Pasc. 

 1882. 



(A.rubrirostris, Pape, 1907) = A. lameerei, Faust, 1899. 



(A. trilineatus, Faust, 1891) = A. siynatus, Boh. 1836. 



A. signatus, Boh., is cited by Bovie (on the authority of 

 Faust) as an African species, but in reality it is 

 Indian ; and all the specimens identified by Faust 

 under this name (cf. Ann. Soc. Ent. Belg. 1899, 

 p. 415) will almost certainly prove to be A. arcuatus, 

 Boh. 



A. roelofsi, Lewis, is omitted from Bovie's Catalogue ; it 

 was proposed (Ann. & Mag. Nat. Hist. 1879, p. 465) 

 as a new name for A. albolineatus , Roel; 1875 (nee 

 Boh. 1836), and A.sexvittatus, Faust, 1894, falls as a 

 synonym of it. 



The genus Accents, Pasc, should not be included in the 

 Alcidinte ; it belongs to the Hylobiinse, being nearly 

 related to Paipalesomus, Schh. 



XV. — On the Varieties of the Lizard Ophiops elegans, Men. 

 By Gr. A. Boulenger, F.R.iS. 



(Published by permission of the Trustees of the British Museum.) 



This lizard, the type of the remarkable genus Ophiops 

 established by Menetries in 1832, the distinguishing feature 

 of which resides in the apparent absence of eyelids *, varies 



* "Palpebra inferior nulla, superioris tantummodo rudimenta," 

 Men6tri6s. — " Oculi palpebris destituti, capsula oculari instructi," 

 Wiegmann. — " Pas de paupieres," Dumeril & Bibron. — " Eyelids none," 

 Gunther. I have long ago set right this misconception. The only 

 character distinguishing this genus from Cabrita, Gray, is the fusion of 

 the lower eyelid with the upper, a state of things conveying the appear- 

 ance of an absence of the eyelids. What was supposed to be the cornea 

 of the eye in Ophiops is the transparent disc of the lower lid, neither 

 more nor less developed than in Cabrita. Although united with the 

 upper, the lower eyelid is, however, not absolutely immovable. On 

 touching the transparent disc in an Ophiops occidentalis which I had 

 alive, I observed this to be at once lowered, the upper half of the eye 

 being then covered by the granular portion of the lid.
