1. Orthoceras (species).

2. Great mult.i.tudes of _Atrypa phoca_, forming, in fact, a dark-colored earthly Atrypa limestone.

14. _Cyathophyllum_ (species).

15. _Loxonema Salteri_, described by Mr. Slater in Sutherland's 'Voyage to Wellington Channel;' Pl. V. Fig. 19.

This is a fine slab of limestone, almost together composed of the remains of _Loxonema Salteri_ and _Atrypa phoca_. It appears to have been quietly deposited at the bottom of a deep submarine depression, swarming with Pyramidellidae and deep-water Brachiopoda. The physical conditions indicated by the fossils are also rendered probable by the rock itself, which consists of fine grey limestone, subcrystalline, and intimately blended with the finest and most delicate description of mud, such as could only be found where the water was deep, and all currents far removed.

A specimen of the same fossil coral which I have named, doubtfully, from Beechey Island, as Favosites or _Calamopora Gothlandica_; it is not impossible, however, that it is not a Calamopora at all, but a species of Chaetetes.

No. VII. POSSESSION BAY, South entrance into Lancaster Sound (Lat. 73 30' N.; Long. 77 20' W.).

Specimens of brown earthy limestone, with a fetid smell when struck with a hammer; resembles closely the limestone of Cape York, Lancaster Sound.
