only in a few cases and then indistinctly are the characteristic spines indicated. 

 As the measurements agree exactly with those of the C. quadrimucronatus, I think 

 the specimens may without doubt be referred to that species. Found associated 

 with other Ftica slate fossils at French Head, Field Bay, and in Countess of 

 Warwick's Sound. 

 Climacogeaptits, sp. 



Many specimens of a form belonging certainly to this genua occur, but none 

 are well preserved enough to allow of a determination of the species. Hydrothecae 

 30-31 per inch. Greatest width 2.5 mm., tapering slowly from greatest width. 

 They occur in the same association as the preceding species, and are closely allied 

 to C. hicornis. Hall, but are much smaller. 



SiCULA OF aEAPTOLITES. 



A large piece of chocolate-brown limestone; contains in immense numbers 

 the embryonic tubes of a species of graptolite, probably of the D. dentatus, above 

 described. These are minute very elongate hollow cones, often flattened; the 

 mouth truncated obliquely, and prolonged in a slender rigid thread about the 

 length of the calicle itself, which latter is 1.5 to 2 mm. long.

A single cup, of the size and shape of the smaller ones figured by Woodward. 

 The lamellae are connected at the bottom by cross plates. In buff limestone. 

 Halysites catenulata, L. 



A single specimen in buff limestone with Pentamerus. 



From Eescue Harbor ; quoted also from Silliman's Fossil Mount of Hall, 

 lat. 63° 44" K, long. 68° 56" W., by E. P. Stevens.— Hall's Nar., p. 594. 

 Stictopoea eamosa. Hall. ? 



Many weathered specimens occur in the gray crinoidal limestone along the 

 north shore of Frobisher Bay. It may be the same as the Alveolites ? arctica.

 Heleolites (new species). 

 Heliopora (new species). 



"The specimens of corals were very perfect and beautiful, and unlike any 

 figured by Professor Hall in the Palaeontology of New York." (R. P. Stevens, 

 Hall's Nar., Appendix X.) 



Crinoid stems and fragments are found abundantly, but in all ca«es round, 

 small, and not determinable.
