§ Resume of principal Muscular and other Characters 

 of Hemisus. 



The principal characteristics of the genus Hemisus which I 

 have been able to elucidate in the foregoing pages, are as 

 follows : — 



(1) The rectus abdominis has but one inscriptio tendinea. 

 It cannot be distinguished laterally fi-om the obliquus 

 externus and is folded over itself at edge of the abdomen, 

 where it joins the thigh, in a remarkable way. 



(2) The obliquus internus consists of a thick layer of muscles,, 

 arising mainly from the dorsal aponeurosis to the outsido 

 of the ilia, which end upon a thin membrane which repre- 

 sents the ventral portion of this muscle. It is uncovered 

 for the greater part by the obliquvis externus. 



(3) The sternohyoid consists of three distinct muscles inserted' 

 separately and behind each other on to the hyoid body. 



(4) There is no omohyoid. 



(5) The submaxillaris appears to be specialized into three 

 tracts on each side, of which the fibres run at different 

 angles to each other. 



(6) The dorsal portion of the depressor mandibulse is present. 



(7) The latissimus dorsi has an origin extending considerably 

 beyond (behind) the scapula and joins early with the 

 infraspinatus. 



(8) There is no rhomboideus muscle. 



(9) There are altogether four " serratus " muscles on each side- 

 of the body ; 1 and 2 arise respectively from the transverse 

 processes of vertebrte 3 and 4; 3 arises from the transverse- 

 processes of both those vertebrae ; 4 arises from the neck 

 laterally in front of the third vertebra. 



(10) In the thigh the rectus internus minor partly arises from 

 the skin. 



(11) There are two pairs of large fat-masses lying in lymph 

 spaces and another pair corresponding in position to the 

 thymus lying beneath the skin. 



(12) The stomach is elongate, with a narrower portion bent to 

 form a U with the major portion. 



(13) The small intestine is traversed throughout by closely set 

 transverse folds. 



(14) The fat-bodies are very large. 



(15) The oviducts are much coiled and with a long drawn out 

 gutter-like funnel. 



(16) The lymph-sacs are not particularly large and in the 

 usual position. 



(17) The hyoid has large extra-hyals anteriorlj^ which fuse 

 ventrally below the hyoglossus muscle, and the body of the 

 hyoid is very thick, with a bony plate distinct from and 

 overlying the convex and swollen cartilaginous layer. 



The above 17 characters appear to me to be the chief anatomical
