it is found to be a poncli full of large eggs, which are about .7 mm. long. In 

 fact, the ovaries are in this species thus pushed beyond the disky somewhat as in 

 Star-fishes. 



Color in alcohol, pinkish or yellowish brown. 



Station 344, 420 fathoms, 3 specimens. 



ASTROSCHEMA Ltk. 

 Astroschema horridum sp. nor. 



Plate XVII. Figs. 458 - 461. 



Special Marks. — Entire surface covered with little, swollen, oblong angular 

 plates or scales, bearing minute points. 



Description of a Specimen (Station 170). — Diameter of disk 12.5 mm. 

 Length of arm 195 mm. Width of arm near disk 4.7 mm ; height of arm 

 4.2 mm. Seven stout, thickened, rather small teeth, of the usual short spear- 

 head shape. The mouth-angles are paved with large, flattened, swollen grains, 

 but have no true papillae. Arms nearly cylindrical, very slightly swollen for 

 their first 20 mm., beyond which they taper very regularly. They are evenly 

 and pretty closely beset with minute points, like little blunt spines, about 4 

 in the length of 1 mm. ; these, on allowing the surface to dry, are seen to stand 

 on small, swollen, oblong, angular plates or scales, which may be considered as 

 exaggerated grains set with points. This covering continues quite to the end 

 of the arm, where, however, the grains are more rounded and without points. 

 Disk thick, rising a little above the arms, elegantly scalloped on its margin, 

 with large radial shields (ribs), which are thick, swollen, and projecting at 

 their outer ends, and taper inward to the centre, where they meet ; its surface 

 is paved with little oblong, angular, swollen plates or scales, rather coarser 

 than those of the arms, and bearing similar minute points. Genital openings 

 straight, and occupying about one half the height of the disk. Mouth-tentacles 

 enclosed in a tube of flat grains ; the next pair has no tentacle-scale ; the next 

 one and those beyond have two, which are short at first, but about 40 mm. out 

 become somewhat suddenly elongated, the upper one, about 1.3 mm. in length, 

 remaining blunt spiniform, while the lower and larger takes on the form of a 

 cylinder 3 mm. long, with a rough, swollen end. The two lines of pores lie 

 closer together than usual, so that the furrow on the lower side of the arm is 

 narrow. Color in alcohol, pale reddish brown. 



Station 1 70, 630 fathoms, 1 specimen. 



Astroschema salix sp. nov. 



Plate XVII. Figs 466-469. 



Special Marks. — Granulation fine, even, and close set; 7 or 8 grains in the 

 length of 1 mm. Disk flat, with ill-distinguished radial shields. At tip of 

 arm the lower tentacle-scale takes the form of a compound hook.
