 after a slight interspace 32 additional spines on median line of back and tail, 2 of the latter being between 

 the dorsals. The spines are large anteriorly, becoming smaller to the root of (he tail, thence larger, as 

 large as the anterior ones for half length of tail, whence they grow gradually smaller to tip of tail. Teeth 

 quite sharp, conical; lateral edges of upper lip fringed; back with small prickles everywhere, except 

 an area below and behind eyes to below shoulder region, and the edges of pectoral laterally and pos- 

 teriorly; a row of pores, with short tubes, on each side and just below the first median spine, these 

 diverging toward each eye, running half the distance from spine to eye, the area about them being free 

 from prickles; a similar row of pores around the entire margin of the disk and also on each side of the 

 nasal cartilage; lateral and posterior angles of disk broadly rounded, margin between these angles 

 gently rounded.
