OF THE SCAPULA IN THE BATRACHIA. 211 



Hylodes Fitz. 



11. raniformis Blgr. — Scapula a little shorter than the prje- 

 coracoid, but well developed. Pars glenoidalis smaller than pars 

 acromialis ; dividing cleft short. 



II. fleischmanni Boett. — In this species the scapula is subject 

 to slight individual variation. It may be equal to or a little 

 longer than the prpecoracoid. 



H. lineatus Schn. and H. martinicensis Tsch. — The scapula is as 

 in H. raniformis. 



The scapula in Hylodes is somewhat like that in Hi/la as 

 regards the relative proportions of the shaft, pars acromialis, and 

 pars glenoidalis. They diiFer, however, in that the dividing cleft 

 is short in Hylodes, forming a very small central foramen instead 

 of a very large one, as in Hyla. 



Ceratophrys Boie. 



G. hole Wied. — ^Scapula greatly developed, once and a half 

 as long as prfecoracoid. Distal end of shaft about twice 

 width of proximal end ; pars acromialis and j-jars glenoidalis 

 normal ; dividing cleft short, forming a very small central 

 foramen ; a small portion of acromion cartilage exposed between 

 head of prjecoracoid and end of pars acromialis. 



In 0. ornata Bell and C. americana D. & B. the scapula is as 

 in C. hole. 



E.vamjiile. 



Length of pr?ecoracoid 10 units. 



,, scapula 15-2 „ 



,, » shaft 11 „ 



Breadth of „ (distal end) 5 „ 



„ (middle) 2-3 „ 



Length of supra-scapula 13'7 ,, 



Leptodactylus Fitz. 



L. pentadactylus L. — Scapula equal to or slightly longer than 

 praicoracoid ; stoutly formed. Shaft broad, half length of praj- 

 coracoid ; pars acromialis well developed, partially separated 

 from head of prsecoracoid by acromion cartilage ; pars glenoidalis 

 well developed, strongly depressed; dividing cleft short and 

 broad, forming an oval foramen, pierced horizontally, hardly 

 visible from outer view. 



L. ocellatus L. — Scapula as in L. pentadactylus, 



Hylorhina Bell. 



H. silvatica Bell. — Scapula as in Hyla. 



Limnodynastes Fitz. 



L. peronii D. &, B. — Scapula well developed, longer than praj- 

 coracoid ; distal end twice the width at the middle. Shaft as 

 long as prsecoi-acoid ; pars acromialis somewhat diamond-shaped,
