Harbour. As they were in shallow water we obtained them easily. 
We observed them on various occasions and at different hours of the 
day, but never saw them show the least sign of movement. Besides, 
they were covered with rather large specimens of Hipponyx which 
appeared to have multiplied there peacefully. This was in the 
month of November. Had these animals assembled in such numbers 
for breeding purposes 1 ? We cannot say. We regret that we did 
not make researches on their sex at the time. All those which we 
brought back in spirit are females. 
In examining the base of Bald Head, we recognised several of 
these same Cerithiums enclosed in limestone between tide-marks. 
We suppose that these shells are not fossil but merely encrusted in 
the rock. 
Turritella granosa, new sp., 1 King George’s Sound. 
Turbo torquatus , Lamk. 2 — This Turbo, which attains a large 
size, inhabits King George’s Sound. We found few living 
individuals. 
Turbo fimbriatus, Lamk. 3 — King George’s Sound. 
Phasianella bulimoides, Lamk. 4 — King George’s Sound. 
Phasianella ventricosa , new sp. — King George’s Sound. 
Trochus irisodontes , new sp. 5 * — King George’s Sound. 
Trochus luteus, new sp. — This Trochus occurs throughout King 
George’s Sound, but principally in the little salt creeks. 
Vermetus arenarius , Lamk. 0 — Inhabits King George’s Sound, 
living, at a considerable depth, on other shells. 
Vermetus dentiferus , Lamk. — Obtained in Sharks Bay on an 
Avicula. 
Stomatella auricula , Lamk. 7 — Our individuals came from the 
same place as the one which is in the Museum (Paris), which Peron 
brought from King George’s Sound. 
Haliotis albicante, new sp. — King George’s Sound, on the rocks 
at the entrance. It is so common that it is surprising that Peron 
did not describe it. 
Parmophorus australis, Lamk. 8 — This Mollusc inhabits King 
George’s Sound, where, however, we only found it on one occasion. 
It lives for a long time in the air, and we watched one climb out 
of the water in which we had placed it.
