 a horny sheath, having eight reversed bristles on each margin. The 

 horns of the hyoid bone pass along the median line of the head until 

 they are over the middle of the eyes, when they tm-n to the right side, 

 and are curved along a deep groove on the anterior edge of the orbit, 

 passing under the eye to opposite its middle. The oesophagus is 3 in-

 meter. The stomach is rather small, elliptical, 9 twelfths long, 8 

 twelfths broad ; its lateral muscles moderately developed. The con- 

 tents are larvae and coleopterous insects. The epithelium is dense but 

 thin, and longitudinally rugous. The intestine is 9 inches long, 2^ 

 twelfths in width at its anterior part. There are no coeca. 



The trachea is 2^ inches long, slender, about 2^ twelfths in breadth, 

 a little flattened, and of about 60 rings. The bronchi are of moderate 

 length, slender, of about 12 half rings. The contractor muscles are 

 moderate ; the sterno-tracheals come oflP close to the inferior larynx,
