CLARK: BERMUDAN ECHINODERMS. 
341 
During my visit in April, specimens were obtained of all the holo- 
tliurians previously recorded from Bermuda, except Synapta inhaer¬ 
ens. Synapta acanthia was found only at the cove in Coney Island, 
and is not abundant there. It is so much larger than inhaerens that 
it is hard to get perfect specimens, as it lives deep in the sand and is 
easily broken. The best specimen I secured was about 35 cm. long, 
but it broke up into several pieces soon after being placed in a 
bucket. In its habits this species seems to resemble inhaerens quite 
closely* A number of specimens of S. vivipara were collected in the 
bright green seaweed ( Ulva) in Bailey’s Bay. They were all green 
in color, somewhat marked with white. In Jamaica where the same 
species lives in a reddish brown seaweed ( Acanthophora ) the ground 
color is reddish brown, though there is often much green pigment 
in the skin. The difference in color makes the appearance of Ber¬ 
mudan specimens very different from that of those from Jamaica. 
I think there can be no doubt that Synapta pourtalesii of Selenka is 
this species. A careful reading of Pourtales’ description, and the 
study of the living animals, has convinced me that the form which 
he described from Biscayne Bay, Florida, as S. viridis (== pourtal¬ 
esii Sel.) is identical with the Synaptula vivipara of Oerstedt, de¬ 
scribed nearly two years earlier. The species has therefore a wide 
range, having been recorded from Bermuda, Florida, Central Amer¬ 
ica, Jamaica and Brazil. The commonest synaptid in Bermuda is 
Synapta roseola (Ver.), though Chiridota rotifera Pourt. is very 
common. These two species were found almost everywhere under 
stones between high and low water mark and in shallow water. 
. They are constantly associated, and are abundant in Bailey’s Bay 
and around Coney Island and occur all along the north shore. The 
Chiridota grows to a much larger size than has been known hitherto, 
for specimens 6 or 7 cm. long were common and one specimen 10 cm. 
long was collected. Many contained young in the body-cavity, indi¬ 
cating that the species is viviparous in Bermuda as it is elsewhere. 
In the collections made by Mr. Carpenter there are specimens of 
S. vivipara. and C. rotifera. Of the former, Mr. Carpenter says: 
“We found it in abundance in “ sea-lettuce ” and another seaweed 
along the Paget shore in Hamilton Harbor. Color of most a reddish 
brown, streaked transversely with white. Others of a greenish 
brown color, also streaked with white.” The absence of S. inhaer¬ 
ens from both Mr. Carpenter’s collections and mine is noticeable. 
Roseola is so abundant that it seems strange that inhaerens should
