SECOND REPORT on the ECHINODERMATA 
of the T.M.B-C. DISMRICI 
_ By Herpert C. Cuapwick. 
(Communicated by Professor Herdman.) 
[Read 8th February, 1889. ] 
In the following pages I have incorporated with the 
results of the work of the L.M.B.C., during the years 
1886-7—8, my own observations on the Hchinodermata 
of Beaumaris Bay and the Menai Straits. 
The total number of species obtained by the Committee 
up to the present time is thirty-five, the additions to the 
previous lists* consisting of five Asterids, viz., Stechaster 
roseus, Asterias glacialis, Solaster endeca, Porania pulvillus, 
and Lwdia savigni, and one Holothurian, Cucwmaria 
planct. The Anglesey coast, from Bangor eastwards, 
round by Puffin Island to Holyhead, and the deep waters 
off the southern end of the Isle of Man, have again yielded 
most of the forms obtained. Though none of the species, 
nor yet of the groups to which they are assigned, can be 
said to be peculiar to any part of the L.M.B.C. district, 
the Asteroidea appear, both as regards species and indi- 
viduals, in greatest force in the latter locality, while the 
Menai Straits are largely inhabited by four out of the 
six Ophiurids recorded in our previous list. 
The Echinoidea are more generally distributed; all the 
recorded species being well represented in both the above- 
mentioned localities; and the same remark applies fairly 
well to the Holothuroidea.
