SIPHO PROPTNQUUS. 375 



convex; spire elongate, gradually diminishing in size towards an acute apex; 

 suture well marked; ornamented by fine spiral ridges and by the lines of growth; 

 mouth ovate, angulate above; canal short, slightly twisted, turning sharply to the 

 left; columella tortuous; outer lip thin. 



Dimensions. — L. 15— 25 mm. B. 6— 10 mm. 



Distribution. — Recent : New England coasts — Massachusetts, Halifax, Eastport, 

 Grand Manan. 



Fossil : Bridlington. 



Remarks. — The fossils from Bridlington here given are from the Museums at 

 Cambridge and York, where they are labelled F. Sabinii and F. curtus respectively ; 

 they agree rather, however, with the American species 8. pygmssus, a specimen of 

 which, by the kindness of Mr. C. W. Johnson, I am able to figure with them for 

 comparison. Jeffreys says, in the paper quoted above, that F. pygmseus is not 

 F. Sabinii, as considered by Wood, and that F. curtus is the American form of 

 F. islandicus. On p. 183, I have adopted the specific name Sabinii for some Crag 

 shells corresponding more nearly with the figures given by Hancock and Jeffreys 

 {op. cit.), while I retain the unsuitable one curtus for the abundant Red Crag form 

 which in his list of Crag shells in Prestwich's paper (p. 492) was clearly identified 

 with the Trophon gracile of Wood's Monograph of 1848 (pi. vi, fig. 10). In any 

 case it is difficult to understand why Jeffreys called it curtus. It is almost 

 impossible to ascertain what his F. curtus really included. From Mr. Headley's 

 Bridlington collection Mr. A. Bell has sent for my inspection two fragmentary and 

 different specimens each bearing in Jeffreys' writing the name of F. curtus. They 

 are not alike and they are not Wood's T. gracile. F. curtus was neither figured 

 nor described by Jeffreys, although in his written allusions to it he claimed the 

 name as his own ; much confusion has arisen in consequence. 1 



Another instance of the same kind exists in the occurrence at Bridlington of a 

 fossil described by Wood as Trophon Lechenbyi (Sipho), ]st Suppl., pt. i, p. 24, 

 pi. vii, fig. 1, which has been dredged also in a fossil condition off the Shetlands ; 

 a form nearly allied to this is recorded by Mr. Friele as Neptunea (Sipho) carta 

 (Norske Nordhav. Exped. (Mollusca), pt. i, pi. ii, fig. 2).

1 The Fusios curtus of Smith was in Wood's opinion a different shell (see Mon. Crag Moll., pt. ii, 

 p. 314).
