Bean founded this species on a specimen found in a Scarborough 

 fishing-boat, but I have not been able to refer to his original descrip- 

 tion and figure to see which of these two forms is the type. (Jeffreys' 

 reference in "British Conchology " is wrong; instead of "Bean in 

 Mag. N.Hist., viii.," it should be "Bean in Loudon's Journal, vol. vii., 

 p. 493, fig. 61.") Canon Norman says the slender (or male shell) is 

 the "typical Doggerbank form,"^ but both forms occur on the 

 Doggerbank as well as in the Shetlands and off the Aberdeenshire 

 coast. He also adds that it is "well figured by Forbes and Hanley,'" 

 but a comparison of the latter's figures and measurements will demon- 

 strate that their type is the large and broad female form. 



Northern specimens are smaller than ours generally, rarely exceed- 

 ing 4in. in length, and these exhibit a still further range of variation. 

 Sars figures several ; Friele has described one as 7^. ossiaiii; and Mid- 

 dendorff another as F. schanta?'icus; while Canon Norman has also 

 described two specimens from Norway, apparently immature, one as 

 var. brevispira and the other as var. tuinida.' Specimens, however, 

 the exact counterparts of the two latter are also found in our seas, 

 some of them much more tumid than his figure, while as regards the 

 short-spired form, some of my British specimens have very little 

 spire indeed, measuring only 4in. in length by 2|in. in width. That 

 both slender and broad specimens also occur in Norway is evident 

 from Sars' figures, as he gives the immature forms both of the male 

 (t. 14, f. 3b) and female (t. 25, f. 10). 



F. schmitaricus Midd.'' possesses no specific attribute apart from 

 F. turfoni, and though Canon Norman "lays chief stress on the 

 spiral grooving of the inside of the lip" (p. 354) tliat is merely the 

 impress of the ordinary outer sculpture, which is occasionally observ- 

 able (also with the purple interior) in the immature stage oi F. furtofii, 

 and more frequently in F. islandiais, a species similarly sculptured. 

 Sars' figure 3 (pi. xiv.) clearly shows the connection between the two 

 forms. F. furtoiii also rejoices in several generic names. Prof Dall 

 has conferred on it that of Beringiits, Herr Friele that ol Jumala, 

 and Canon Norman that of Ukko.
