connect with the symphysis. Such a band would have an 

 analagous position to the hgament anterior to the coracoid in 

 Aphanfophri/ue, and it is reasonable to presume that it was along 

 such lines that the remarkable ligament of this new genus 

 evolved. 



Notes on the Pectoral Myology of Aphantophryne pansa 



COiMPARED with THAT OF LiMNODYNASTES DORSALIS AND 

 Kaloula PULCHRA. 



The interesting nature of the pectoral muscles of Aphantophryne 

 pansa, revealed by the dissection to examine the sternal apparatus 

 of the type-specimen, has led me to prepare the following notes. 



It wuuld have been more satisfactory' to have reserved any 

 anatomical investigation till more suitably preserved material 

 came to hand, but the variation of the breast-muscles is of such 

 an unusual nature, and is so directly related to the most interest- 

 ing taxonomic feature of this new form, namely, the absence of a 

 sternal plate, that any notice, however superficial, will, I think, 

 be of present interest. It is hoped that the poor condition of 

 my material has led to but few serious errors. 



The pectoral musculature of several members of the family 

 Brevicipitida? (Engystomatidye auct.) has been dealt with by Dr. 

 F. E. Beddard, in a series of papers published in the Proceedings 

 of the Zoological Society of London. T must acknowledge the 

 great assistance I have received from these fine papers, and have 

 gleaned from them the main points of accord and discord, and 

 intercalated them briefly below. 



For comparative purposes, two hitherto unfigured frogs are 

 illustrated, and briefly described. One, Limnodynastes dorsalis 

 var. dunierilii Peters,* belonging to the family Cystignathidae, 

 has a complete arciferous pectoral girdle. The other, Kaloula 

 p^dchra Gray,t belonging to the same family as Aphantophryup, 

 and systematically not far removed from it, has a firraisternal 

 girdle with no clavicles or omosternum, but difl:ers from it in
