A Week in Gaspe. 329 



of those I have been able to determine, whieh it may be of interest 

 to compare with the list of Post-pliocene fossils from Montreal, 

 and of recent shells collected by Mr. Bell in Gaspe, given in pages 

 414 et seq., of the last volume of this Journal. 



Marine Invertebrates collected in Gaspe Bay, JV. Lat. 48° 45', 

 August 1858. 



Articulata. 



Homarus Americanus. — The common lobster is very abundant, and 

 might be obtained in large quantities for exportation. 



Platycarcinus irroratus.—Very abundant, especially near the fishing 

 stations. 



Maia. — A large spider-crab, apparently of this genus. Fragments 

 from stomach of a halibut. 



Pagurus Bernhardus. — Young specimens inhabiting shells of small 

 Buccina, found in stomach of cod. 



P. Icevis (Thompson). — A specimen was dredged, on sandy ground, in 

 the shell of a small natica, which I cannot distinguish from this species. 



Cythere. — A small species, perhaps undescribed. In mud in deep 

 water. 



Balanus crenatus. — Common on stones near the shore. 



B. Porcatus. — On stones in ten fathoms. 

 Coronula diadema. — On skin of whales, 



C. RegincB (Darwin). — On shreds of the skin of the humphback 

 whale in one of the whale houses, we found a specimen which corres- 

 ponds exactly with Darwin's description of this species, hitherto ob- 

 tained only from the Pacific. It is full grown, being nearly two inches 

 in diameter, and was imbedded nearly to the summit in the skin. It 

 may be easily distinguished from the common whale barnacle, C. dia- 

 dema, by its flattened form, its low and smooth ribs delicately marked 

 with radiations and transverse ribs with minute tubercles at the inter- 

 sections, and by the thinness of its radial plates. It would be inte- 

 resting to know if this cornula is peculiar to the humpback, which is 

 very probably an Arctic species visiting both the Pacific and Atlantic. 



Spirorbis Sinistrorsa. — Stones and weeds, six to ten fathoms. 

 S. quadrangular is. — Same habitat. 

 Serpula vennicularis. — Same habitat. 

 Several species of Nereids not determined. 



Mollusca. 

 Loligo illecebrosa, — Squid. — Common, and caught for bait by mean3 

 of a lead sinker having a circle of pins fixed in its lower end. 

 Fusus pyramidalis (rufus). — Stomachs of cod. 

 Buccinum undatum. — Stomachs of halibut and cod. 

 B. trivittatum. — Dredged in sand near the shore, four fath. 

 Purpura lapillus. — On stones near the shore.
