OF TIIE SCAPULA IN THE BATRACHIA. 207 



In the following species the scapula is as in 11. maxima : — ■ 

 H.faber Wied, //. albomarginata Spix, II. boans Daud.,.//. taurina 

 Fitz., H. venulosa Laur., H. nigromaculata Tscliudi, U. domini- 

 censis Bibron, H. versicolor Lee, H. pulchella D. & B., H. arborea 

 L., H. macrops Blgr., H. coerulea White, H. dolichopsis Cope, 

 H. aurea Less., H. lesuearii D. & B., H. nasuta Gray, H. gratiosa 

 Lee. 



In II. lichenata Gosse and H. baudini D. & B., the scapula is 

 a little longer than the prsecoracoid. 



Although Hyla is a very large genus, it will be seen that the 

 scapula is remarkably stable in its proportions. It is not of 

 much use, however, as a diagnostic character, as it is of the form 

 most commonly met with in this family. 



NoTOTREMA Gthr. 



iV. marsupiatum D. & B. — Scapula elongated, once and a 

 quarter as long as prsecoracoid, very slender in the middle. Shaft 

 as long as prsecoracoid ; pars acromialis and pars glenoidalis as in 

 Hyla maxima. 



Pternohyla Blgr. 



P.fodiens Blgr. — Scapula as in IT. maxima. 



Nyctimantis Blgr. 



JV. papua Blgr. — Scapula as in H. maxima. 



Agalychnis Cope. 



A. moreletii A. Dum. — Scapula as in H. maxima. 



Phyllomebusa Wagl. 



P. dacnicolor Cope. — Soapula abnormally developed, about twice 

 as long as prsecoracoid, and about twice and a half as long as 

 broad at distal end. Shaft about once and a quarter as long 

 as prsecoracoid, very slender, expanding at distal end ; pars 

 acromialis not in contact with head of prsecoracoid ; pars 

 glenoidalis very much reduced, branching widely from pars 

 acromialis ; central foramen very large, oval. 



P. bicolor Bodd. — Scapula similar in form to that of P. dacni- 

 color, but even more developed in length, being twice and a 

 quarter the length of the prsecoracoid. Shaft once and three- 

 quarters the length of prsecoracoid ; pars acromialis separated 

 from head of prsecoracoid on outer surface hy acromion cartilage, 

 in contact on inner siirface.
