30 MARSHALL: ALTERATIONS IN ‘BRITISH CONCHOLOGY.’ 
Obviously, a quarterly journal is utterly inadequate to keep 
us au courant with the change of systems ; we shall almost 
require a daily tape to record the movements of ‘our ad- 
vancing knowledge.” 
Tectura fulva Mill. Both Mr. Dall and Professor Sars have 
examined the animal of this species, and declare it to 
be a true Zepefa. The name should therefore be changed 
to Lepeta fulva, although Dall places it in the sub-genus 
Pilidium, and Sars in the sub-genus Scutellina. 
Emarginula cancellata Phil. This was figured though not 
described in “ British Conchology,” and inserted in Somer- 
ville’s List. But I fear there has been some error as to its 
origin. Herm has been well searched since the two 
alleged specimens were taken by Mr. Gallienne thirty years 
ago, yet no further examples have been found, and Mr. 
Gallienne’s collection in the Guernsey Museum certainly 
does not contain these two specimens. I think it should 
be put in the same category as other species that have had 
a supposed origin in Guernsey and Herm. 
I have myself found in the latter island a perfect 
specimen of £. elongata Costa. This differs from £. 
jissura in being more depressed, with much coarser though 
similar sculpture, the apex overhangs the margin, and the 
slit is shorter and wider. Many currents converge on Herm 
Island, and some of its little bays and shores are strewn 
with shells knee-deep. 
Scissurella crispata var. paucicostata Jeff. In the 
‘Lightning’ Report Jeffreys states that Philippi’s var. 
aspera corresponds with his var. paucicostata, and is 
‘‘more conical, with fewer and stronger striz.” The latter 
name must, therefore, be withdrawn in favour of the former. 
Trochus duminyi Requien. Circudus striatus Phil. is prior 
to Z. duminyi, and must take its place. Philippi originally 
described it as ?Valvata striata; Cantraine afterwards 
redescribed it as Solarium philippi, and Requien subse-
