402 PROCEEDINGS OF THE ACADEMY OF [Sept., 



Unfortunately, the case was somewhat complicated by a short note 

 which I mailed from Europe and published in the Proceedings of the 

 Biological Society of Washington (Vol. XXII, April 17, 1909, p. 89). 

 This note read as follows: 



"A correction is to be made in the case of Cacopoioles borealis Bar- 

 bour, described as the type of a new genus and species in a paper on 

 'Some New Reptiles and Amphibians' (Bull. Mus. Corny. Zool., Vol. 

 50, No. 12, p. 321, April, 1908). It appears that this must now be 

 considered identical with Callula verrucosa Boulenger, though consider- 

 ably variant from the type of that species and vastly removed from it 

 in range. Boulenger's specimen came from Yunnan, while that on 

 which the supposed new species was based was collected at Antung, 

 Manchuria." 



Drawings have been prepared to show not only the difference in 

 outward appearance between the two species but the shapes of the 

 terminal phalanges, the sacral diapophyses, the sterna, and the inter- 

 iors of the mouth cavities. In some cases drawings illustrate the form 

 of the same structures in the allied genus Cacopus. A comparison of 

 these figures will serve to show graphically and more satisfactorily the 

 differences than would a lengthy verbal description. 



For the sake of record the original description is appended herewith 

 from the Bulletin of the Museum of Comparative Zoology (Vol. LI, No. 

 12, April, 1908, p. 321 ) : 



Cacopoides gen. nov. 



An engystomatid related to Cacopus. The precoracoids are wanting, 

 the coracoids meet each other on the median line, without an inter- 

 calated cartilage; the large metasternal cartilage, instead of being 

 connected to the coracoids by an isthmus, much more narrow than the 

 metasternum itself, is closely adpressed to the coracoidal symphysis. 

 This may be made more clear by the appended drawings. Choanal 

 small, with valve-like flaps ; dermal ridges behind the choanae converg- 

 ing posteriorly and each with an enlarged papilla near the median line; 

 another long ridge in front of the oesophagus which is sharply curved 

 anteriorly near the median line. Tympanum hidden. Fingers free, 

 toes webbed at base, tips not dilated. Sacral diapophyses rather 

 strongly dilated. 



Cacopoides borealis sp. nov. 



Habit very stout. Head small ; snout rounded ; no canthus rostralis ; 

 snout about as long as orbital diameter; interorbital space more than 

 twice the diameter of the upper eyelid. Fingers moderate, first shorter
