In well-preserved specimens the whole tractus intestinalis exhi- 

 bited a deep black colour, not produced by the contents of the stomach 

 and of the intestines, but by a pigment deposited in aU its membranes. 

 There are four pyloric appendages, of the same intense black colour. 

 The other abdominal intestines have the usual colour. The pos- 

 terior third of the ovarium is united, the two anterior ones separated. 



STceleton. — The very fine, velvet-like vomerine teeth form a rather 

 acute angle ; those of the palatine bones are situated in a narrow 

 biserial band. The prseorbital bone is rather flat, the others slightly 

 concave, with entire edges : of the edges of the praeopcrculum only 

 the posterior part of the external margin is minutely serrated. The 

 ridge of the frontal bones is low, the groove not deep, which is in 

 accordance with the less-developed canalicult mucosi of the other 

 parts of the skull in this species. There are ten abdominal and 

 fourteen caudal vertebrae.
