270 Miscellaneous. 



Amplexus, CyatJioplit/lhim, and Arachnojihullum were noticed, and 

 correlated with British forms when possible ; but, on the whole, the 

 facies of the Coelenterata is American rather than European. Amongst 

 the Crustacea five genera were noticed : — Bronteus, Cah/mene, En- 

 crinurus, and Proetus, all Upper Silurian ; and the genus Asaphus, 

 associated with Maclurea, of Lower Silurian age. Ten species of 

 Brachiopoda, belonging to the genera Pentamerus, Rhynchonella, 

 Chonetes, Atrypa, Strophomena, have been detennined. 



Collections were made from twenty localities, ranging from lat. 

 79^ 34' to 82° 40' N., notably the highest, at Cape Joseph Henry, 

 where Capt. Feilden obtained a numerous Carboniferous-limestone 

 fauna, numbering about thirty species, chiefly Brachiopoda and Poly- 

 zoa, all determined species, and American in character rather than 

 British. Mr. Etheridge believed ho had determined, through certain 

 forms of Brachiopoda, the presence in a ravine at Dana Bay of the De- 

 vonian rock below the Carboniferous Limestone south of Cape Joseph 

 Henry and Feilden Isthmus, the want of plant-remains preventing 

 any correlation with the Ursa stage of Heer. It cannot now be 

 doubted that an extensive Silurian fauna extends to, and is present 

 from lat. 79° to lat. 82° N., illustrating both the lower and upper 

 divisions of this groiip of rocks, especially the equivalents of our 

 Wenlock series. Again, north of these there sets in a clearly 

 defined Carboniferous-Limestone fauna, reaching the extremity of 

 the highest latitude we know, and probably striking away beneath 

 the Polar sea to Spitzbergen, where the same species have been 

 described by Toula. The authors, through certain fossils, then 

 endeavoured to show that on the whole the facies of the Polar 

 palaeozoic fauna was more nearly allied to that of America than 

 to that of Europe, and thus must be correlated with it, although it was 

 shown that a large number of species are common to the two areas, 

 especially the British Islands. The absence of Lamellibranchiata in 

 rocks older than the Tertiary was noticed as having special interest 

 in the physical history of the Polar seas in Palaeozoic and Mesozoic 

 times. None have ever been detected in these rocks. The authors 

 stated that they had sought also for evidence of Trias and Permian 

 fossils in this and other collections made, but there appeared to be 

 none. They also discussed the question of the deposition and exten- 

 sion of the Lias as represented at Eglinton Island and Spitzbergen. 

 The authors furnished a Table showing the distribution of all tlie 

 species collected by the expedition from twenty localities.

Probable Distribution of a Spider by the Trade- Winds. 



Rev. H. C. M'Cook states that the Sarotes venatorius, Linn., a 

 large laterigrade spider of the ballooning kind, occurs, according to 

 specimens in his private collection, from Santa Cruz, Virgin Isles,
