Body depressed, much elongated, nearly uniform in breadth through 

 out; back convex; ventral surface flat. The whole dorsal surface is 

 closely covered by the imbricated scales, of which there are more than 

 150 pairs. These, with the exception of the anterior and posterior pairs, 

 are broadly lunate, with a deep emargination in the center of the ante 

 rior edge; the posterior and lateral margins are broadly rounded ; the 

 outer lateral edge is laciuiately fringed; the posterior edge is smooth; 

 the whole surface of the anterior scales is covered with minute, slightly 

 elevated granules ; farther back, the exposed portion of the surface of 

 the scales is smooth, and the microscopic granules are restricted to the 

 anterior and inner portions. The scales of the anterior pair are oval, and 

 have their entire outer and anterior margins minutely but irregularly 

 denticulate. 



The head is small, rounded, contracted behind the posterior eyes and 

 in front of the anterior ones ; the eyes are near together, in a quadran 

 gle ; those in the anterior pair are a little farther apart, and lateral. 

 The head is prolonged anteriorly into a narrow elliptical or oval portion, 

 which forms the base of the median antenna ; close to and below each 

 of the anterior eyes a prominent, membranous, ciliated process arises. 

 The feet of the first pair, which are directed forward, are elongated, and 

 bear a pair of slender, elongated, dorsal cirri, which are nearly as long- 

 as the antennoe; a much shorter, slender cirrus from the lower lobe, with 

 a small, thin, membraneous process below ; and a large fascicle of long,
