the case of a specimen of T. cinerarins. Other species have been 

 found occasionally in a similar condition, as well as several instances 

 of Fusus. I consider that in all such cases they have been swallowed 

 by fish, partially digested, and then voided again. 



The scalariform monstrosity is very pretty and rare. A subscalari- 

 form one has 'been recorded from Menai Straits {J. Conch., vol. 7, 

 p. 28); and Mr. J. E. Cooper found another monstrosity at Jersey 

 having a double operculum. 



T. occidentalis Migh. — Aberdeenshire (Simpson) ! off Aberdeen, 

 58 f., and off Montrose, 53 f. (' Triton ') ! off the Doggerbank, 44 f., 

 80 miles N.E. by E. from Scarborough. My largest specimen, from 

 the latter district, is half-an-inch in length and breadth. 



Var. pura Jeff. — Aberdeenshire (Simpson and J.T.M.); Dogger- 

 bank. 



I have T. cinerens Couth., dredged dead, and probably fossil, from 

 Eigg Island, 20 f. ; Clyde, 15 f . ; Gairloch, 30 f. ; Loch Boisdale, 30 f. 

 "A young and dead specimen, but apparently recent," was dredged 

 by the ' Porcupine' off the west of Ireland in 173 f. 



Other outlying species are T. suturalis Phil, and T. ottoi Phil. = 

 T. rhysus Wats., from the Faerce Channel (!) 



Two specimens of a new species of Trochus (Calliosto/ua) were 

 dredged off the south-west of Ireland, in 200 f., in the Royal Irish 

 Academy cruise of 1886, one specimen containing the animal and 

 operculum. It is a handsome shell, unlike any other British species 

 of Trochus, and very much resembles the new genus Gaza (G. dce- 

 dala) of Watson. 



Phasianella pullus L. — There are two forms everywhere, denot- 

 ing the sexes. The male has the body-whorl more circumscribed, 

 with a slightly longer spire — it leads into the var. oblotiga, but the 

 latter is still more slender, and the last whorl is not much wider than 

 the penultimate one. That of the female is, more globose and has a 

 shorter spire. All the British writers figure the shell of the male as 

 their type, and that, according to Monterosato, is not Linne''s. 



Var. oblonga Jeffr. — Guernsey; South Devon; Weymouth. 



Var. pulchella Reel. — This very distinct variety is the preva- 

 lent form at Guernsey and Herm, where it takes the place of the type, 

 and is also found at various other places. It differs from the type in 

 being much smaller, subconic instead of oval, the spire longer and less 

 rapidly increasing, the last whorl proportionately smaller, and especially 

 in the colour never varying, but being always pink. L. 0*2, B. C125 

 inch. It is easily recognisable at all stages of growth, and also the 

 male and female forms. From var. oblonga this is but half the size,
