are attaelied to the parent near the mouth by a cord or umbilicus and 
there they live until able to shift for themselves, the development being 
without a metamorphosis. 
It has usually five rays, which are slender but not contracted at base. 
The ambulacral furrows are deep, the tube-feet not forming four dis- 
tinct rows. On the hack, towards the disk, five longitudinal rows of 
spines may be distinguished, which become irregular towards the tips 
of the rays. The spines of both back and sides bear a small crown of 
minor pedicellarijc [i. e. the small pedunculated ones borne on the 
spines]. The madreporic plate is surrounded by a circle of spines and 
there are few or no major pedicellarhc. The papulae or water-tubes 
of the back are placed singly and not in clusters as in A. vulgaris. 
In color it is of a pale flesh color or white. It is about two and one- 
half inches in diameter. Nothing is known of its habits, and its develop- 
ment, as mentioned above, is direct. 
[Prof. Verrill, in a letter to the writer, says : — “J. conqHa, bt., I have 
from the Bay of Fundy, and I am inclined to think that J. teuera is 
only a slender variety of it.” It is, however, left as a separate species 
in this paper, as Prof. Verrill has not published his comparisons of the 
two, and the writer has not been able to examine specimens of A. 
cornpla.'\

Prof. Verrill now considers that this species was not well founded. 
He says, (S) : — “I have become satisfied that the species descri bed by 
me as A. Stimpsoni in 1866, was not well founded. The study of a 
far more extensive series of specimens has shown that the specimens- 
thus named were somewhat peculiar small specimens of A. vulgaris 
(Stimp.), with which some young specimens of A. Uttoralis were also 
confounded, so that the characters given largely appertain to then 
young of H. vulgaris^ J
