There seems to be much difference of opinion respect- 
ing Crisia elongata and its varieties. My own speci- 
mens from South Africa differ from Mediterranean 
specimens even from the same depths as Mr. Waters’s 
deep and shallow water forms. Mr. Waters gives the 
following synonyms, which, at present, I cannot 
accede to: OC. fistulosa, Busk; (?) 0. Hdwardsii, 
Reuss; (?) C. Edwardsii, Manzoni. 
11. ,,  Edwardsiana, D’Orb., Busk, p. 5, pl. i. figs. 5-8. 
= (?) Bicrisia Edwardsiana, D’Orb., 1852 
= Crisidia Edwardsiana, D’Orb., 1839, ‘ Voy. dans. 
lPAmér.’ 
Geogr. Distrib.: Coasts of Patagonia, D’ Orb. ; Tierra 
del Fuego, Darwin; New Zealand, Dr. Sinclair; 
Australia, Maegil. 
Mr. Busk says: ‘ D’Orbigny’s figure represents the zocecia as much 
longer and more slender than his own specimens; but he has retained 
his name because he has but little doubt about the identity of his own 
and D’Orbigny’s species.’ 
12. Crisia eburneo-denticulata Smitt (MS.), Busk, pl. vi. 
= Crisia eburnea (var.) Smitt. 
Loc.: Spitzbergen, 70-96 fathoms. 
13. ,,  acropora, Busk, pl. v. figs.3,4, Id., ‘ Voy. of Rattles.,’ vol. i. 
p- dol.

gonia (Dr. Sinclair). 
oe. Holdsworthii, Busk, pl. vi.a, fig. 2. Loc.: Pearl-oyster 
Bank, Ceylon (Holdsworth). 
16. ,,  conferta, Busk, pl. vi. a, ig. 5. Loc.: Cape Verd Islands 
(H.M.S. Herald). 
17. ,,  tubulosa, Busk, pl. vi. a, figs. 3,4. Loc.: Cape Verd Islands 
(H.M.S. Herald). 
These are the whole of the species of Crisia illustrated by Mr. Hincks, 
Mr. Busk (‘ Cyclostomata’), and Mr. Waters (‘ Bay of Nap. Bry.’). Mr. 
Busk, however, gives a list of other recent forms noticed by authors 
(see ‘Cyclos.’ pp. 7 to 9).
