FUSUS. 93 



raliter lirato ; apertura pyiiformi. — Not knowing this shell, I 

 give a reduced copy of the figure (152). The cancellated 

 structure of the upper whorls distinguishes F.latcriceus from 

 others of the same group. 



127. ri'LLUS, f. 142, Reeve. — Testa ovato-oblonga, lsevis- 

 sima; spira producta obtusa, anfractibus 6 brevibus rotundis; 

 apertura brevi, intus purpureo-castaneo, canali brevi, truncato. 

 — A smooth shell with rounded upper whorls of a greyish 

 buff colour. Inside of mouth dark chestnut. 



128. glaber, f. 148, Verkrutzen. — Testa F. gracili simili 

 sed laevigata, vix lirata, magis ventricosa. — The spiral sculp- 

 ture is very slight, and the shape is more sloped and the 

 whorls less distinct than in Islandicus. 



129. obesus, f. 92, Sowerby. — Testa magna alba, pyrami- 

 data, ventricosa, spiraliter leviter sulcata ; spira producta, 

 anfractibus 7 declivibus, paulo prominentibus ultimo ventri- 

 cosissimo subelongato, infra latissimo, apertura lata, subpyri- 

 formi, canali brevi, subtortuo. — The shell in the late Mr. 

 Taylor's collection, from which this figure and description are 

 taken, bears a somewhat near resemblance to F. Glaber, Ver- 

 krutzen, but is more bulbous at the lower part. 



130. ventricosds, f. 98, Gray. — Testa globosa alba, epi- 

 dermide viridi induta, spiraliter lirata, spira brevi, anfractibus 

 6 rotundis, rapide crescentibus, ultimo globoso; apertura 

 subpyriformi, canali brevi tortuo. — A very bulbous shell of 

 the northern series, to which F. Islaridicus and F. gracilis 

 belong. 



131. solidulcs, f. 97, Sowerby. — Testa bulbosa, fusi- 

 formi, laevigata albida, epidermide lutescenti nitenti induta, 

 leviter striata ; spira acuminata, anfractibus 5 brevibus, 

 declivibus subrotundis, ultimo subgloboso, apertura subaurea 

 pyriformi, lata, canali producto tortuo. — In form this shell 

 much resembles the young and more fusiform state of F. 

 ventricosus as figured by Reeve under the names F. striatus, 

 Rve., in the text, and F. ventricosus, Gray, in the Index. It 

 is, however, distinct, being more heavy, as well as more 

 fusiform, and pointed at both ends. 



132. ebor, f. 150, March. — Testa ventricoso simili sed 

 canali latissime et brevissime truncato. — Not knowing this 

 shell, I have lithographed the figure from a tracing procured 

 by the kindness of a friend. It may, however, be the stri- 

 atvfi of Gray.
