REPORT ON THE ASTEROIDEA. 623 
small spines on the adoral margin of each plate, which are directed horizontally over the 
buccal membrane, and radiate slightly apart, forming an elegant comb of six spinelets at 
each mouth-angle. The spinelets are subequal in length, invested with delicate membranous 
sheaths, on which are borne several comparatively large pedicellariz. On the actinal 
surface of the plate is a single, comparatively large, and robust secondary or superficial 
spine, about 2 mm. in length, often, and perhaps normally, slightly flaring at the tip. 
This spinelet was invested with membrane, but I am unable to remark upon the character 
or number of the pedicellarize borne upon it. 
The madreporiform body, which is small and rather inconspicuous, is somewhat more 
remote from the margin than usual in the Brisingidx. It is very simply punctured, a single 
figure-3-shaped striation and one or two isolated irregular pores being all that I can detect. 
Colour in alcohol, a light dirty ashy grey. 
Locality.—Station 171. North-east of the Kermadec Islands. July 15, 1874. Lat. 
28° 33’ 0” S., long. 177° 50’ 0” W. Depth 600 fathoms. Hard ground. Bottom tem- 
perature 39°°5 Fahr. ; surface temperature 66°°5 Fahr. 
Remarks.—Freyella polycnema differs from all the other species of the genus by the 
great number of its rays, by their delicacy, and by its small size. With the single excep- 
tion of Freyella pennata, a large robust form with ten rays, it is the only other species 
with three true mouth-spines on each mouth-plate. By the above-mentioned characters, 
as well as by other minor points of detail, it may be readily distinguished from all the 
known species. 
3. Freyella echinata, n. sp. (Pl. CXIL figs. 1-5). 
Rays eleven. R= 202 to212mm.;r=12mm. R>177. Breadth ofa ray at the base, 
6 mm. ; at the widest part of the ovarial inflation, 9 mm., which is measured at a distance 
of about 18 mm. from the junction with the disk. At 40 mm. beyond the disk the width 
of the ray is 4°5 mm., and about midway between the base and the extremity, 3°2 mm. 
Rays of great length and delicacy, cylindrical and narrow at the base, thence gradually 
swelling into a robust, but not greatly tumid, fusiform ovarial inflation, occupying less 
than the proximal fifth of the length (actually 37 mm.), beyond which the ray is sub- 
triangular, with a truncate carination, and tapers gradually to a very attenuate extremity. 
The disk is small and slightly elevated above the level of the rays at their base, with 
the abactinal surface probably capable of slight inflation ; in its present condition rather 
concave, which is somewhat emphasised by the moderate prominence of the basal arches of 
the rays, formed by the ambulacral plates at their junction with the disk.’ The ovarial 
inflation is not so great abactinally as laterally, hence the concavity seen in the profile 
view of the ray, intervening between the elevated margin of thé disk and the ovarial 
inflation, is not so deep as in some species.
