408 MR. F. E. BEDDARD ON THE ANATOMY 



covered by the liver in the species Breviceps gihhosus. There is, 

 however, as I have illustrated by fig-iires *, some individual 

 difference in the liver in this genus. 



§ On certain Characters of the Skeleton. 



I did not notice particularly the sternum of the other species of 

 Breviceps ; in B. c/ibbosus the form is not at all as it is figui-ed by 

 Parker in his ' Monograph of the Shoulder-Girdle ' t, nor is it 

 like the woodcut given by Boulenger in the ' Catalogue ' J. The 

 cartilaginous j)late is much more important than would be 

 gathered fi'om those figures, and expands laterally into a curved 

 and thinnish process. It is, in fact, very like the sternum of 

 Discoglossus pictus as figured by Boulengei' §. 



Two other features in the skeleton of this frog were commented 

 upon by myself in the earlier account of the anatomy of this 

 genus. I naturally endeavoured to ascertain if those peculiarities 

 were to be found in Bremceps gibbosics, and I find that the 

 species which forms the subject of the present notes has the plate 

 of cartilage lying upon the exjDanded sacral transverse process, 

 and that the anterior cornua of the hyoid are perforated in 

 exactly the same fashion Ij. I need not give a more prolonged 

 description of these peculiarities, which appear to be identical in 

 the two species. 



§ On certain Muscles. 



Many of the muscular peculiarities of the species described in 

 my earlier paper occur also in the species now under consideration. 

 It is, perluips, important to enumerate such of these as I have 

 verified, in order to confirm them — for they ai-e unusual — and 

 also in order to point out that they are apparently characteristic 

 of this genus or at least of more than one species. I shall not, 

 however, give a long description of them. In the first place, the 

 latissimus dorsi (see text-fig. 131), not a very large muscle, is 

 completely covered over by the double sheet of the obliquus. 

 There is also no trace of the posterior part of the dejjressor 

 mandibular. I did not note in my paper whether the cephalic 

 portion of this muscle was present. I find that it is present 

 in B. gibbosus. In the present specimens also the suprascapula 

 is largely exposed anteriorly when the skin is removed, on account 

 of the absence of the posterior part of the muscle just referred 

 to. It is covered, however, by a tough fascia. Furthermore, 

 the dorsal muscle of the suprascajDula, the infrasjnnatus, is quite 

 visible without removing any other of the dorsal muscles. 



The rectus abdominis is nearly as in Brevice'ps sp., where 

 I have figured it. In B. gibbosus I could find one superficial
