CylindreUa. Mr. Bland has discovered the presence of a jaw, composed of 
numerous overlapping plates, in eight species, Ann. & Mag. Nat. Hist. ii. 
p. 389 ; see also Journ. Conch, xvi. p. 316. He figures the jaw of C. irini-' 
taria in Am. Journ. Conch, iv. p. 187. [In consequence of this discovery it 
has become necessary to transfer this genus from the Agnathes to the Gonio- 
gnathes, and the following genus, Eucalodium, is rendered rather doubtful.] 
Eucalodium, II. Crosse and P. Fischer establish this now genus on Oylin-- 
drella ghieabreghti (Pfr.), having found an arcuate, finely striate jaw, and the 
lingual teeth disposed in transverse rows of equal size, only the median being 
a little smaller and tricuspidate, whilst in CylindreUa sanguinea they could not 
find a jaw. The rows of teeth are very oblique, the lateral few in number (12, 
in ghieabreghti 32, on each side), of twisted form, and very different from the 
median. To Eucalodium would very probably belong the larger Mexican 
species with filiform keel at the base — decollata (Nyst), grandis (Pfr.), sjden- 
dida (Pfr.), turria (Pfr.), clava (Pfr.), speciosa (Dkr.), and boucardi (Sallt5)-
