■678 MR. F. E. BEDDARD ON THE [June 16, 



NOTARTHRINUS BINGHAMI, Sp. n. 



Agrees with cle Niceville's description of Bothria chenneUii, 

 except that it is without the discal line on the upper side of the 

 fore wing, and the 6th spot of the row on the under side is all but 

 obsolete. A more important difference is that in this row of spots, 

 the first one in chennellii is in line with the others, in hinghaini 

 it is markedly moved inwards, as in argiolus and many other 

 'Cyanirids. 



I cannot help a suspicion that de Niceville had these two 

 species, chennellii and binyhami, mixed (Col. Bingham, also, had 

 not separated them), and when referring chennellii to Cyaniris 

 had hinghaini in view. 



Type in Col. Bingham's collection. A cotype in somewhat finer 

 condition is in the museum at Tring. Col. Bingham's specimen 

 is from Shillong ; the Tring specimen is labelled " Khasia Hills, 

 Assam."

 unfortunately mounted on the slide too far off to come into the photo-

(Text-figures 143-149.) 



I have examined a number of examples of this small Chilian 

 Engystomatid Frog which were presented to the Society by 

 Dr. E. P. Reid some months since. This examination enables me 

 to add something to what is already "known concerning this Batra- 

 chian, the breeding-habits of which are so remarkable and now so 

 well known through the investigations of Gay, Espada, Howes and 

 others, especially and most recently Prof. Biirger, for the loan of 

 whose memoir written in Spanish I am indebted to Dr. Reid. 

 Dr. Biirger * and Prof. Howes t give lists of the memoirs 

 relating to this species, which I need not therefore recapitulate 

 here. The contributions made respectively by the two 

 authorities mentioned deal with the gulai- sacs, their structure 

 and development. Incidentally some information is given in 

 these papers concerning the visceral and muscular anatomy with 

 which I have occupied myself for some time past ; and so far as 

 the facts go I am able to confirm those authors. As, however,
