ASTROPHYTID^. 

 Astroschema intectum sp. nor. 



Plate III. Figs. 59-61. 



Special Marks. — Arms very long and slender, granulated above, but naked 

 on the sides and under surface. 



Description of an Individual (Off Havana). — Diameter of disk 11.5 mm. 

 Length, of arm about 280 mm. Width of arm close to disk, ■without spines, 

 3 mm. Teeth longer than broad, with a curved cutting edge, the lowest one 

 often split. Arms long and slender ; the arm-joints are indicated by annular 

 swellings. Radial shields long, and meeting in the centre ; their granulation 

 is finer than rest of disk, there being eight or nine in a mm. long, but only six 

 or seven on the rest of the upper disk. Granulation on the arms more scat- 

 tered and smaller, and confined to the upper surface, the sides and under 

 surface being quite naked. No tentacle-scales usually on the first pair of arm- 

 pores ; on the second, and those beyond, there are two, long, blunt, and spini- 

 form, whereof that on the brachial side is much the longer. This spiniform 

 scale grows much larger toward the middle of the arm, but is never club- 

 shaped. Genital openings short and wide. Color in alcohol, pale flesh with 

 a disk grayish above. 



Sigsbee, off Havana, 175 fathoms, 2 specimens. 



Astroschema arenosum sp. nov. 



Plate III. Figs. 63 - G4. 



Special Marks. — Granulation coarse and rounded. Tentacle-scale of the 

 interbrachial side growing long, but scarcely club-shaped. 



Description of an Individual (Station 2). — Diameter of disk 9 mm. Width 

 of arm close to disk, without spines, 4 mm. Teeth longer than broad, with a 

 bluntly pointed cutting edge. Arms rather stout and of moderate length, but 

 stiff with the coarse granulation which covers their entire surface ; the joints 

 are dimly indicated above and on the sides by slight s\vellings. Upper disk 

 coarsely granulated about five grains in the length of a mm. ; those on the 

 arm are not so closely set. Radial shields not quite meeting in the centre, 

 much wider without than within. Genital openings short, but rather wide. 

 The first tentacle-pore has no scale ; the next two have one, .short, rounded, 

 and spiniform ; the rest have two, that of the interbrachial side being small : 

 the other continues to grow larger till it equals two arm-joints in length, 

 when it is thorny at the end, but scarcely swollen. Color in alcohol, white. 



This species approaches nearest to A. oligactes, which has, however, a sharp, 

 almost spine-like granulation, and much shorter tentacle-scales. 



Station 2, 805 fathoms, 1 specimen. Station 35, 804 fathoms, 1 specimen.
