OF THE SCAPULA IN THE BATilACIIIA. 207 



In the following sjDecies the scapula is as in H. maxima : — • 

 H.faher Wied, //. albomargbiata Spix, H. hoans Daud.,i/. taurlna 

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

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

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

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

 Lee. 



In //. Uchenata 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 chai-acter, as it is of the form 

 most commonly met with in this family. 



NOTOTREMA Gthr. 



N. 7narsupiatum D. & B. — Scapula 'elongated, once and a 

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

 as long as prsecoracoid ; ;?«rs acromialis and joars glenoidalis as in 

 Hyla maxima. 



Pternohyla Blgr. 



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



Nyctimantis Blgr. 

 , N. fapiui Blgr. — Scapula as in H. maxima. 



Agaltchnis Cope. 



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



Phyllomedusa Wagl. 



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

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

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

 as pr.«BCoracoid, very slender, expanding at distal end ; pars 

 acromialis not in contact with head of prsecoracoid ; joars 

 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 praecoracoid. Shaft once and three- 

 quarters the length of prsecoracoid ; pars acromialis separated 

 from head of praecoracoid on outer surface by aci'omion cartilage, 

 in contact on inner surface. 



Example. 



Length of prsecoracoid 10 units.
