ON A COLLECTION OF BATRACHIA AND REPTILIA FROM THE 



ISLAND OF HAINAN. 



BY E. D. COPE. 



The collection on which the following notes are based was made 

 by the Rev. Francis Gilman, who sent them to Prof. Chas. S. Dolley. 

 Prof Dolley placed them in uiy hands for identification and descrip- 

 tion. 



Hyla arborea var. 



This form agrees in structural features with the true H\jla arborea 

 of Europe, but differs in coloration, not only from this but from the 

 two subspecies which are known from Eastern Asia (H. a. chinensis, 

 and S. a. japonica). 



The extended hind limb marks a point between the eye and the 

 nostril with the heel. The vomerine teeth are between the internal 

 nostrils, but the posterior borders of the fasciculi are behind a line 

 which connects their posterior borders. The diameter of the tym- 

 panum is about half that of the eye; and the interorbital width is 

 greater than that of an eyelid. The length of the head to a line 

 connecting the posterior borders of the tympana, enters the total 

 length 3.2 times. The fingers are slightly webbed, and the toes are 

 about two-thirds webbed. There is a heavy glandular fold from the 

 orbit to the shoulder. 



The color is uniform green above, and uniform pale (perhaps yel- 

 lowish) below. There are no spots of any kind anywhere. A light 

 brown band extends from the eye through the tympanum and disap- 

 pears about the shoulder. It has neither dark nor pale borders, and 

 is hence very indistinct. A similar band extends from the eye to 

 the nostril. Upper lip not pale bordered nor spotted. Total length, 

 40 mm.; do. of hind leg from* groin, 59 mm.; of hind foot, 27 mm. 



Holarclius doUeyanus sp. nov. Plate X, fig. 1. 



Scales in seventeen rows. Superior labials eight, all higher than 

 long, the fourth and fifth entering the orbit, the sixth in contact with 

 the inferior postocular only, the seventh in contact with the lower 

 postocular, and more extensively with the parietal. Loreal trape-
