wards direct, the tip acute and at its extremity descend- 

 ing obliquely. The cere is of moderate length, fea- 

 thered on the sides, its margin forming a convex curve 

 before the nostril, below which it passes directly to the 

 edge of the mandible. The lower mandible is straight, 

 its crura narrow and flexile, the angle elongated, wide 

 and rounded, the very short dorsal line slightly convex, 

 the back and sides convex, the latter toward the base 

 slightly concave, sloping outwards and cerate, the edges 

 soft and meeting those of the upper until near the end, 

 where they are sharp and inflected, their outline de- 

 curved and with a single slight sinus on each side, the 

 tip obliquely truncate. 



The mouth is very wide ; the palate prominent, slop- 

 ing upwards at the sides, with a short central and two 

 lateral prominent lines, converging forwards. The pa- 

 latal slit is narrow-elliptical behind, anteriorly linear. 

 The tongue is small, narrow, fleshy, sagittate and pa- 

 pillate at the base, its upper surface with a central 

 groove, its tip thin and slightly bifid. The oesophagus 

 is very wide, of nearly uniform diameter, it being about 

 ten-twelfths across when dilated, slightly contracted at 

 the commencement of the proventriculus, which is half 

 an inch long, with thickened walls, the glandules large 

 and very distinct ; its inner coat smooth and glistening, 

 like a serous membrane ; its entire length five inches. 

 The stomach is nearly globular, a little flattened, an 

 inch and three-fourths in diameter ; its tendons distinct, 

 and nearly half an inch in diameter, the fibres of its 

 muscular coat rather coarse. The intestine, which is 

 twenty-two inches long, is wider at its upper part, 

 where it has a diameter of three-twelfths, gradually di-
