posits. In the outer layer of the body-wall are large numbers of 

 well-developed tables, with discs wliich normally contain four 

 central holes and four larger and eight smaller ones in the 

 periphery ; the spire terminates in 20^24 teeth and has one or two 

 cross-bars. Underneath the tables is a layer of very numerous, 

 long, thin buttons usually with nine pairs of holes. At the base 

 of the tentacles and in the skin of the oral disc are numerous, 

 slightly knobbed or branched rods, and there are numerous other 

 rods somewhat similar to the supporting rods of the tentacles. 

 The pedicels, however, seem to have no other supporting rods 

 than the long buttons. The C-shaped bodies, such as are found 

 in many species of Stlchojms, seem to be wanting." 



The species seems to bear a close resemblance to SticJiojJus 

 jolmsoni Theel reported from Santa Barbara, California. The re- 

 lations of the two species ought to be re-examined.
