comb. The papilloa along the genital slits, which begin at the inner end 

 of the mouth shield, are short, close set, square, almost as large as the papillae 

 of the arm-comb; c. 8 papilljB to be seen from above (Figure 5 shows a 

 little too many). Often some of the papillaB are smaller than the others 



There is a secondary arm-comb (Plate VII. 

 Fig. 4), consisting of a row of papilla3 along the upper part of the outer 

 edge of first side arm-plate, (that is to say the first which reaches the dorsal 

 side of the arm,) and on a little supplementary plate, which lies at the upper 

 end of this side plate. 



Four quite rudimentary, equally spaced arm-spines. Tentacle pores 

 large, distinct to the end of the arm, first pair opening into the mouth space. 

 Numerous tentacle scales : the first pore with five to six on the outer (abra- 

 dial), four to five on the inner (adradial) side; second to third pore with 

 four to five on outer, four on inner side ; fourth pore with four to five on outer, 

 three on inner side; fifth to eighth with four to five on outer, two on inner 

 side; ninth to about the fifteenth with three to four on outer, one on inner 

 side. From this point there are no papilla) on inner side, two or three on 

 outer side, and these continue to the end of the arm. The outermost of the 

 papilte on the inner side is larger than the others; of those on the outer 

 side the same is the case with the first pore; on the second pore the inner- 

 most papilla is the largest, and from the third pore they are almost all equally 

 large. The direction of the pores gradually alters farther out on the arm : 

 on the inner part they are at an angle of c. 45" with the longitudinal axis 

 of the arm, farther out they are at right angles with it. 



Color in alcohol : grayish white. 



Stations : 3431, 995 f., 5 large specimens ; 3419, 772 f ., 1 large specimen.

Plate II. Figs. 1-3. Plate V. Fig. 3. 



Diameter of disk, 7 mm. ; width of arm close to disk^ 1.4 mm. ; length of 

 arms unknown, as they are broken in all the specimens at hand. Five 

 short, square, close set mouth papillfB on each side of the mouth angle, one 

 pointed on the apex of jaw. Mouth shield large, with an acute angle 

 .within, outer edge rounded, lateral sides restricted; the outer part is much 

 broader than the inner part; a Httle longer than broad. Side mouth shields 

 very long and zaarrow, meeting within.
