3G8 Verrill, Notes on Badiata. 



Echinaster (Othilia) crassispina Ven-iii sp. uov. 

 Plate IV, fig-lire 1. 



Rays short, somewhat anguhited. Radii of disk and rays as 1 : 4. 

 Interambulacral spines, two to each plate, the outer ones being large 

 and short, forming a close, regular row along the border of the ambu- 

 lacral groove ; the inner one much smaller, not half so long, and 

 forming an inner row concealed l»y the others. Along the lower side 

 of the rays and well separated from the interambulacral spines, there 

 is a row of distant, large, conical, sharp spines, about fifteen in nmnber, 

 which do not extend upon the disk, and gradually diminish in size 

 toward the end of the rays, where they are very small. Upon the 

 sides and back of the rays there are four or five less regular rows of 

 similar large, sharp, distant sjiines, arising from the swollen nodes of 

 the reticulated plates. Disk naked beneath, above Avith few large 

 spines, like those of the rays. Surface smooth, in the spaces between 

 the spines pierced by many small pores. Color briglit crimson when 

 living ; in alcohol, dull reddish brown ; when dry, deep purplish brown. 



Radius of disk -5 of an incli ; of rays, 1-9. 



Bahia, Brazil, — C. F. Hartt. Three specimens. 



This remarkable species difiers widely from E. spin.osiis in its shorter 

 and more angulated rays, coarser plates, and much fewer and stouter 

 spines. Also in the spineless disk beneath, and much larger and more 

 crowded outer interambulacral spines bordering the grooves. It dif- 

 fers from E. multispina Gray sp. [E. Braziliensis M. and Tr.) in liav- 

 ing much fewer and larger spines aljove, and different interambulacral 

 spines. 



Asterias Atlantica Verriii, sp. nov. 



A small specimen having eight rays, four of wliich are smaller than 

 the others, was obtained at the Abrolhos Reefs liy IMr. Hartt. Another 

 specimen with six equal rays, which is in my possession, collected at 

 Bermuda by J. Matthew Jones, Esq., does not appreciably differ 

 in structure. Two other specimens, one of which has seven unequal 

 rays, and the other, which is much larger, five regular ones, appear to 

 belong to the same species. These are believed to have been collected 

 at Remedios, Cuba. 



This species may be recognized by the very slender, blunt interam- 

 bulacral spines, which form a single row along the edge of the ambul- 

 acral groove ; by the crowded double row of larger ventral spines, 

 very near the interambulacral, the spines being long, round, tapering, 

 not pointed, and arranged two upon each plate ; by the regular lateral 

 row of distant, long spines, larger than the ventral, and mostly only
