BATRACIIIA SAIJENTIA. 95 



the inferior part of the tympanic and with the malar ; this process 

 approaches the joint, without being in connexion with it ; the os 

 pterygoidenm appears to be entirely separated from the tympanic, if 

 looked at from above, but both are luiited beneath without any 

 visible suture. Thus also the malar is partly iinited with the tym- 

 panic bone. The parietals are relatively verj^ narrow, not quite half 

 as broad as the frontals, leaving a great space for the united temporal 

 and orbital grooves ; they have an irregularly serrated and trimcated 

 front edge, and a pair of spinous prominences behind for the insertion 

 of muscles of the neck. The frontals are the largest bones of the 

 whole skull, subtriangular, with a flat smooth surface ; the two upper 

 ridges of the occipital bones are very prominent, obliquely situated ; 

 petrosal conspicuously separated by sutures. The palatine bones are 

 elongate, as generally, but without a sharp ridge. The diapophjses 

 of the seven middle vertebras do not differ very much from one 

 another, either in length or in direction ; those of the third and 

 eighth are nearly horizontal ; those of the ninth vertebra are very 

 thick, trihedi'al, with rounded ridges ; the coccygeal style is provided 

 with a rather high ridge, and equal in length to the vertebral column, 

 formed by the eight posterior vertebrae. The clavicula styliform, 

 much weaker than the ossa coracoidea, which, much dilated at the 

 inner end, form a long suture and give much fu'mness to the thorax ; 

 the processus xiphoideus, much dilated in front, less behind, is formed 

 by a single bone, and has a broad half-ossified cartilage behind ; the 

 manubrium sterni styliform, and bifid behind for the articulation with 

 the clavicles ; supra- scapula broad, half- ossified ; humerus not much 

 longer than fore-arm, with a moderate ridge near its head ; the iliac 

 bones are rather broad, channel-shaped, with the concavity bent in- 

 wards, both nearly parallel to one another ; femur cyhndrical, with- 

 out ridge, rather shorter than the cms ; the first cuneiform bone 

 very small. 



The intestines exhibit no peculiarity, except the liver, both halves 

 of which are nearly entirely separated from one another : an ex- 

 ceedingly naiTow band of the parenchyma passes behind the heart, 

 \initing both halves. The gall-bladder is small, not immediately 

 attached to the parenchyma, but suspended by a fold of the perito-
