before it had ceased to bo coutinental, but after Iieland and the Isle of 

 Man had become separated from it. Unio Eoisgyi Forbes found in the 

 river at Kii-k Braddon, and -we there picked up some fragments of tho 

 valves. 



The young Nattiralist records finding the bone (so called) of the 

 cuttle-fish on the Manx coast, but the animal is in reality somewhat a 

 southern species ; we got a large mass of the ova of another cephalopod 

 (Ommastreph''s todarus) off the Calf, resembUng in everjthing but size 

 those of Sepiola. To the naked-gilled molluscs which he records in the 

 Malacologia must be added the beautiful Deiidronotus arhorescen.'s from 

 near the same place, and the fine Dons tuberculata or Argo found on 

 Conaster and elsewhere, as in a cavern at the foot of Peel Castle rock ; 

 also Eolis viridis and Aplysia at Douglas. Of the shelled gasteropods we 

 got Capulus Hungaricus, Emarginula fissura* andiFissurella Grceca from the 

 Eamsey scallop-bed, as Porbes had already done ; Trochus 21ontagui and 

 tumidus, Douglas; Acmaa tesfudiiialis, ^eaoasej ; A. rirginea, much raore 

 common than the last on scallop shells ; Trophon clathratus ; lastly, Chiton 

 Asellus and cancellatus, F. and H., must be added to the list.f Of the 

 common limpets, under the name of flitters, the poorer Manx make their 

 Boup. 



As regards bivalve molluscs we might expect to meet with 

 Brachiopoda in the deeper water around the island, and our friend 

 found a single specimen of Crania at Ballaugh. Eamsey is rich in 

 bivalves. I found a specimen of Isocardium cor there, many years back, with 

 the valves still united by the hgament ; also Pecten tigrinus, li\nng, in the 

 Bcallop-bed ; TeUina incarnata, Douglas ; Venus verrucosa, fine Uving 

 species of this southern species, both at Douglas and Ramsey ; Tapes 

 aurea and decussata ; Solecurtus candidus ; Psammobia TelUnella, Douglas, 

 by the dredge ; these, with the exception of the last species, are not in 

 Malacologia Monensis. We append in a note a list of other species, all 

 of which we have found, but which are generally in that work, J also of 

 Crustacea, mostly brought up by the dredge or in the lobster pots.§ 



We dredged Com'itula rosacea off Douglas, but get it much finer 

 between Port Erin and the Calf, from the source already alluded to. 



♦ My specimens appear to be E. MUUeri. 



+ Also fine specimens of Trochus Magus and zizijphinus, with a white 

 variety of the latter found on Conaster Bock, JBullcea aptrta, yatica Alderi. 



I Biy-'lve Mollnsca — Lima fragil'S, Bamsey scallop-bed; Cardium Norvegicum ; 

 liuHna flexiiosn, Ij.horealis ; Lucinop^is un'data, Bamsey; Cyprina Islandica,

 data. Kumsey, V. gullina; Psammobia Ferroennis, Bamsey by the dredge, P. ves- 

 pertina less plentiful than the last. Add also Tellina crassa et alise, Donax anatina 

 (miliar, nitidn), yucula margnritacta and tenuis, Pectnnctclus Glucimfris. Solen 

 mnrainatuH, Syndosmya iiiterm,cdia et ahse, Annniia striata founil on the inner 

 surface of Pectens, very delicate, the lower or perforated valve convex, thongh often 

 scarcely present.
