tilirliopuji califormcu.1 : 



circles and smooth margin ; spire 

 built of four pillars with one or two 

 transverse beams ; crown with com- 

 paratively long, pointed teeth, 10 or 

 more in number. Buttons (c) in a 

 layer below the tables, not thickly 

 crowded but scattered more or less 

 sparsely. They seem more numerous 

 in the ventral perisome. Rather 

 large, with 5 — 8 pairs of holes. I 

 can hardly find any with nine 



pairs of holes as stated by ClAEK. Tables ; r_Button. {x300). 



These buttons form the supporting reds of ventral pedicels which 

 have well-formed end-plates. 



Eemarlis : — Stimpson's description is very unsatisfactory. It 

 runs as follows : " Body much elongated, of nearly the same 

 thickness throughout ; below, flattened and thickly covered with 

 stout sucker-bearing feet not arranged in rows. Dorsal surface 

 with about forty large conical cutaneous processes (or false feet) 

 sparingly scattered ; between which there are numerous cirriform 

 feet also diskless. Tentacula twenty, short, peltate with broad 

 discs. Color reddish brown ; below lighter. Length 1 J feet ; 

 thickness 1^ inches." 



Clark (lOOla, pp. 104 — 1(35) says of the species: "Its position 

 in the Genus Sticliopus is suggested by the flattened ventral surface 

 and the large warts and papillai on the dorsal side, and is clear- 

 ly proven by the arrangement of the genital gland in two tufts, 

 one on each side of the mesentery. It reaches a length of over a 

 foot and is dark brown in color. It is easily distinguished from 

 otlier members of the genus by the remarkable calcareous do-
