Characteristics. Ashen grey, with brownish transverse bars across the tail. Dorsal as high 

 as the depth of the body. Length six to ten inches. 



Description. Form irregularly four-sided posterior to the vent, the lower side being largest ; 

 anterior to the vent, the body is polygonal, and covered with horny plates. Above, the sur- 

 face of the back is depressed, and this is produced by the union of a series of carinated plates, 

 which cause a ridge on each side. This ridge is minutely pectinated, and the plates them- 

 selves are vertically striate on the sides. Sides of the body vertical, and covered by a 

 series of carinated plates, which ascend at the vent, and unite at the termination of the dorsal 

 with the carinated plates on the back. Twenty-five of these plates were counted from the 

 opercle to the end of the dorsal. The abdomen is formed by three series of carinated
