MAEINE ZOOLOGY. 13 



In Echinodcrmatn, what immediatelj- struck us on our first hauls of the 

 dredge in Brodick Bay, and again and again in Lamlash Bay, was the 

 gorgeous coloiu- displayed by the lovely star fish, Goniagter Templetoui 

 (Templeton's cushion star.) It was of bright scarlet above, varied with 

 cloudy whitish markings, and of straw-colour beneath. TNTien living 

 there is a peculiar v-iscosity about the animal — the colour soon fades in 

 confinement. But the brilliant coloiir of this star fish, as well as that of 

 others of the class, served to dispel the popular notion, in those of us 

 whose experience had been limited to a southern fauna, that as one 

 proceeds northward colour diminishes m intensity. The following is a 

 list of the Echiuodei-ms : — Antedon romceux (the rosy feather star)^ 

 many specimens in the free or adult form, taken oif Holy Island. In 

 brittle and sand stars we took numerous specimens of Ophiocoma 

 helliis, 0. gramdata, and O. rosiila ; also Ophiura ie.rturata, Vraster 

 glaciali-s, (the spiny cross-fish,) and U. nihens, (the common cross-fish,) the 

 former very fine specimens — the latter in many instances renewing lost 

 parts. Crihi'Ua ivsea, (the rosy cribella,) one specimen, {tiro only are 

 recorded in " Brj-ce ;") Sohister endcca, (the purple sun star,) one specimen 

 only, (of this beautiful star fish only on" is recorded in " Bryce ;") .S'. 

 pappoffa, the common sun star, several specimens. GonUister Templctoni 

 (Templeton's cushion star) was taken numerously, and was most interest- 

 ing, as indicating the connection — as the late Professor Ed. Forbes 

 pointed out — ^between the true A-'tenudo', and the Echinidcp., both in the 

 general form and the shape of its spines. Aster ias auvantiaca (the 

 Butthom) was represented by one specimen. Echinus sphara (the 

 common Egg Urchin) was taken plentifiiUy ; and a few specimens of 

 Echinus miliaris (the purple-tipped Sea Urchin). Echiiwcyamus pusillus, 

 (the green-pea urchin.) one specimen only. Holothuriad<z were notably 

 absent, if we except a solitary specimen of Thyone papiUosa, (the 

 common Thyone.) This, which is not in the local hst, was most 

 valuable, as showing the passage of the class towards the Annelida. 

 The linear an-angement of the suckers pecuHar to the class is, in this 

 genus, replaced by a diffused series spreading over the whole extent of 

 the body. In Annelida oiu* principal captm-e was AVrntTfcs Borlasii, so 

 graphically described by the late Eev. Chas. Kingsley. Crustacea were 

 represented hy about twelve species, in which Stenorynchus and Inachus 

 were conspicuous ; all are refen-ed to in the local list. In Polyzoa we 

 took Salicornaria farciniinoides, (aUve,) but in this class the specimens 

 were not very numerous — nor were those of the Tunicata. In the class 

 MoUusca, many specimens were taken which space will prevent recording. 

 The most noteworthy (taken alive) were Lima hians, Scajjhandcr liynarius, 

 Dentalium entalis, and Ajwrrliais pies-pelicani . All these greatly interested 

 us, but especially Lima hians. Several "nests" of this remarkable 

 bi-valve were taken, in each case tenanted only by a single indi^idual. The 

 "nests'" themselves consisted of comminuted shells, stones, &c., formed 

 into a matted cluster by their byssal threads. TMien the animals were 

 removed and placed in a vessel of sea water, their great beauty was 

 apparent — some of the tentacles which had become detached remained 

 apparently alive for some hours afterwards, twisting about Uke small 

 earth wonns. In the yudibranchiata we dredged a single specimen of 

 Elysia viridis — not recorded in " Biyce." This animal is exceedingly 

 interesting, as belonging to the order Pellibranchiata, wherein the 

 respiratory function is effected by the whole surface of the bodj% which 

 is clothed with vibratile cilia. In the class Pisces, which terminates the 

 collection, our most interesting finds were a few specimens of both 

 the pretty little sucking fishes, Lepidoyaster bimaculatus and L. Cornu- 

 biensis. They were very small, and the colours were not very well 

 marked. I expect they were immature specimens. One, which was 

 unfortunateh" lost, exhibited markings of a beautiful pale gi-eeu colour.
