and perfect specimens of Gouldia modesta, and have for the 
first time observed the cartilage, which is not possessed by any 
Astarte. Mr. Wood has also obligingly allowed me to examine 
his specimens of A. excurrens. Of course no part of the liga- 
ment is preserved in the Crag shells. The first-named species, 
therefore, must be placed in the genus Crassatella. Thetis 
(afterwards changed to Gouldia) of C. B. Adams is merely a 
synonym of Crassatella. Neither the American nor the English 
eminent conchologists of the same name noticed the cartilage 
or internal ligament in their descriptions of Thetis and Gouldia. 
Astarte and Crassatella are closely allied. C. modesta and 
A. excurrens have a great resemblance; and, in both, the 
ridges are (to use Mr. Wood’s own words in his description of 
the latter species) “ subconcentric, deviating a little from the 
lines of growth,” so that at least one of the ridges disappears 
on the anterior side. 
Verticordia granulata.—I have now dredged specimens of 
this species, as well as of V. acutecostata, pat in size to 
those from North Japan.

Gadinia Gussonii of Costa, not of Scacchi. G. excentrica, 
Tiberi, is probably distinct. 
Emarginula Adriatica—Read E. cancellata. The first-

ela.—Footnote, for * dread” read “ drear.” 
Pyramidella lexiuscula.—The specific name should be that 
given by Bronn, plicosa. See Herr Weinkauff's notices in 
the * Bullettino Malacologico Italiano,’ vol. iii. p. 97 
Solarium Archite—Read S. fallaciosum. The former 
species is flatter, with a rounded periphery, and it has a much 
larger and more open umbilicus. 
Pleurotoma carinata.—Professor Seguenza does not appear 
to have read what I said in the fifth volume of ‘ British ped 
chology ' (p. 222) as to the specific name, when he published 
his article in the third number for this year of the ‘ Bullettino 
Malacologico Italiano.’ 
PTEROPODA. 
Clio pyramidata.—'This and the following two species 
belong to the genus Clio, not Cavolina. By a mistake in 
writing or printing, the letter C did duty for both genera.
