 of this row on the basal pordon of the club. Horny rings of

 after the third sucker of the dorso-marginal row (counting on 

 of the club, the smaller of the marginal rows. Fixing appar- 

 largest tentacular suckers (Figs. 16, 19, 23) toothed all around 

 with about 15 distant, short, stout, conical, pointed teeth, 

 alternating \nth an equal number of short, mde, rectangular 

 plates, the upper median tooth only very slightly larger than 

 its neighbours. Hornv rings of lateral suckers on the club

 toothed all around A\-ith about 17 acute, conical teeth with 

 swollen bases, which on the superior margin of the ring are 

 long, slender, curved, and alternate A\ith about 11-12 usually 

 very minute, conical interstitial teeth becoming rudimentary 

 and finally obsolete below. Horny rings of small cai'pal 

 suckers (Figs. 15, 22) \\ith relatively much smaller apertures 

 than the other suckers, their iipper margins armed with 7-8 

 very large, closely placed, conical teeth, the median apt to be 

 somewhat the largest ; lower margins of these suckers ex- 

 panded, not toothed, usually bearing an irregular ridge near 

 the middle.
