Gdaé6é Litorina, p. 805. Cyclonema octavia, D’Orb. (Siluria, 2nd ed. pl. 
24, fig. 4. Turbo carinatus, Sil. Syst. t. 5, 
fig. 28). 
: Eunema, Salter. 
Silurian and Cambrian rocks. Species are 
_sure to be found. The shells are thin, and 
probably had no operculum. They resemble 
Cyclonema (Geol. Surv. Can. Decad. 1, p. 29). 
Trochonema, Salter (Canadian Decades, No. 1). 
Shells like Hunema and Cyclonema, but with 
a wide open umbilicus, Cyclonema has none. 
Gdé Trochonema bijugosa, Salter (n.sp.). A spe- 
cies much resembling the Z. (Turbo) tro- 
chleatus of McCoy and Hall. 
Macrocheilus? (Polyphemopsis, Portlock). Ovate 
shells, with closely pressed narrow whorls, 
looking more like a Bulimus than anything 
else. They are found in Cambrian as well 
as Silurian rocks. 
FC Machrocheilus pupa, n. sp., Salter. 
Euomphalus, Sow. 
FC p. 297. Euomphalus centrifugus, Wahl. sp. (Hisinger, 
Ge Leth. Suec. t. 12, fig. 1). 
FC p. 298 Euomphalus discors, Sow. (Siluria, 2nd ed. 
Ge pl. 24, fig. 12). 
Gd5 CPN Euomphalus, varieties of ditto. 
FC Euomphalus pacificatus, Salter. 
FC Euomphalus Maria, Salter,n.sp. Related to 

E. discors, but with most regular ridges of 
growth. A beautiful shell, dedicated to a 
most worthy lady—the patient preparer of 
this Collection. Two or three hours daily 
were given by Mrs Fletcher to this task, 
and the result is an unique cabinet of spe- 
cies new to science.
