88 SUPPLEMENT TO THE CRAG MOLLUSCA. 



Capulus ungaricus, Linn. Crag Moll., vol. i, p. 155, Tab. XVII, figs. 2 a — g. 



Localities. Cor. Crag, Sutton, Ramsholt, and near Orford. Red Crag, passim. Fluvio- 

 marine Crag, Bramerton (Woodward). Middle Glacial, Hopton. 



All the above localities for this shell are within my own knowledge except the Eluvio- 

 marine of Bramerton, where, according to Woodward's list in White's ' Directory,' is said 

 to occur small and rare. The specimens from the Middle Glacial are very young ones. 



Capulus recurvatus, S. Wood. Crag Moll., vol. i, p. 156, Tab, XVII, fig. 3 / (as 



C. mi.lita.ris, Mont.). 



Localities. Cor. Crag, Sutton, and near Orford. Red Crag, Walton, Sutton, 

 Newbourn, and Waldringfield. 



The name of militaris given by Montagu to our species being posterior to that given 

 by Linne to a different shell inhabiting the West Indies must be abandoned. I, there- 

 fore, fall back upon the name recurvatus given in my Catalogue of 1842, for the specimen 

 shown in fig. 3/ of Tab. XVII, of ' Crag Moll/ Figs. 3 b, c, d, may be the young of 

 C. ungaricus. 



Mr. Bell has described in the 'Annals and Mag. Nat. Hist.' for September, 1870, 



a shell from the Red Crag of Waldringfield as a new species under the name of C. incertus, 



the specimen of which he kindly submitted to me. He has also (' Ann. and Mag.,' 1871) 



given the name Brocchia sinuosa to the shell shown in ' Supplement,' Tab. VII, fig. 26 a, b, 



which may be the same as Patella sinuosa, Brocchi. In the monograph of the ' Crag 



Moll.' I showed one of these sinuous forms of the Capulidce, under the name var. partim 



sinuosus of C. militaris, regarding it as an accidental variation due possibly to the 



adherence of the shell to a Pecten. Looking at the various forms figured by Prof. 



Salvatore Bionde (' Estr. dagl Atti dell Acad. Gioenia de Sc. Nat./ Vol. XIX, Sec. Series, 



1864) in his monograph of the so-called Genus Brocchia, and at the specimen figured in 



' Supplement,' Tab. VII, I must admit that the idea of an adherence to a Pecten will not 



explain these features. Bionde's figures of some twelve forms under the generic name 



Brocchia show one or more sinuosities in each, but they are not all in the same part of 



the shell nor in the same direction. Neither do they appear in the young shell, but only 



upon that part of the shell which must have been formed after the animal was half 



grown ; and, however caused, suggest the idea that these peculiar features are due to 



some accidental circumstances besetting the growth of certain individuals of the genus 



Capulus. Under these circumstances I do not see my way to the adoption of the genus 



Brocchia until further investigations, especially on living forms if such be discovered, 



have demonstrated that this testaceous covering pertained to an animal generically
