authorities who have worked out the subject. The TomHn collections 

 contain a series of intermediate specimens that could be assigned to 

 either the type or the variety, and either assignation would be correct. 



With respect to my contention that Forbes and Hanley figured 

 another shell in mistake for the var. gracilis, Mr.. Sykes is good 

 enough to say that he is " unaware what authority there is for the 

 statement that the figure represents a different species to that 

 described."^ The authority of course is my own, whatever that may 

 be worth ; but if corroboration were needed it may be deduced from 

 Forbes and Hanley's own words, which I quoted. 



var. monterosatoi Marsh, non E. monterosatoi (De Boury 

 MS.) Monterosato. — This has been figured by Mr. Sykes as a new 

 species under the name of E. collinsi? The figure is a good one so 

 far as it goes, and well indicates the outlines and proportions of the 

 shell. 



My citation of var. monterosatoi for this variety of E. philippii arose 

 from the misinterpretation of a note from the Marquis di Monterosato, 

 who sent me a specimen, asked if it was known to me, and if so 

 whether I could forward him British examples, with others of var. 

 gracilis for comparison. I did so, and in his reply he quoted the 

 names of E. gracilis Forbes and E. monterosatoi De Boury for the two 

 forms, without explaining that one was a synonym of the other, 

 whereupon I concluded that the monterosatoi form was a new variety, 

 and so adopted it. 



E. ? perminima Jeff. — I am not satisfied with the position of the 

 shell placed by me under this name,'^ but as there is only one speci- 

 men I leave it here provisionally. The Marquis di Monterosato, who 

 has seen it, writes me—" Not E. perminima from author's type in my 

 collection." But he does not venture to assign it to any other 

 known species. Nor does the figure of it^ give any help ; the latter, 

 when magnified, looks Hke an adult E. philippii var. gracilis, but 

 when compared with a young specimen of the latter of the same size, 

 this minute shell seems strikingly different. 



E. subumbilicata Jeff. — Two specimens of a Euiima, dredged 

 by the Scottish Fishery Board off the Butt of Lewis in 545f., have 

 been assigned by Mr. Simpson to this species, as they agree "in most 

 particulars " with that species, except that they are transparent and 

 glossy instead of " creamy white " (which is the normal difference 

 between a fresh and a dead Euiima'), and " the last whorl is nearer 

 half the length instead of two-thirds."^ Gwyn Jeffreys' E. subumbilicata
