lanthina. A general account of this genus is given by Jefireys j varieus 
species, as communis (Lam.), glolosa (Swains.), pallida (Harvey), and cxigua 
(Brug.), have been carried northward by the Gulf-stream j and one, rotundata 
(Leach, MS., Dillw.), pi. 8. fig. 1, is occasionally cast on shore from July to 
November in the south and west of England, Ireland, and the Bristol 
Channel. Brit. Conch, iv. pp. 174-189. 
GASTEOPODA. 
S. DE Luca and P. Panceri state that the secretion of the 
salivary glands contains 3-4 per cent, of free sulphuric acid, not 
only in Dolium galea, in which this had been previously observed 
by Troschel in 1854, but also in Tritonium nodiferum, corruga- 
turn, cutaceum, hirsutum {^succinctura^'\, Cassis sulcosa, Cassi- 
daria echinophora, Murex trunculus, M. brandaris, and even 
Aplysia camelus. Ann. Sci. Nat. viii. pp. 82-88. 
In a general description of the radula of the JSolididce, Run. 
Bergh states that the number of teeth in one row is not always 
the same in difiPerent individuals of equal size of the same spe- 
cies, or even on both sides of the same individual, and therefore 
that it cannot be relied upon for specific distinction. Of course 
this is only the case where the number is rather large. He con- 
firms the s^tement made by Troschel, that the teeth are formed 
in the pulpous mass and gradually advance from behind, the 
foremost being lost ; but he agrees with Dohrn [and Crosse] in 
opposing a classification of mollusks exclusively based upon the 
radula. Bergh, ^Eoliderne, pp. 34-36.

H-i Siphonal fasciole is the zone generally differentiated by sculp- 
ture which at its end forms the internal boundary of the si- 
phonal notch or canal. As its modifications and relations are 
often of considerable importance and serve to distinguish genera 
and higher groups, it is deserving of a distincf name. Tii. Gill,
