4. New fossils from the Lower Cambrian, — Mr. C. D. Walcott 

 describes, as new, in the Proceedings of the U. S. National 

 Museum, \ii, 33-30, Kutorgina Labradorica var. Stoantoneneie, 

 Swan ton and Highgate Springs, Vt.; Obolella Atlantica, Eastern 

 Newfoundland and North Attleborough, Mass.; Camerella minor, 

 Stissingville, Dutchess Co., N. Y.; Coleoloides (new genus) typi- 

 cal is, a shell near Hyolithes, Manuel's Brook, Newfoundland; 

 Hyolithes terranovicus and II. eimilie, same locality as the pre- 

 ceding; Helen ia (new genus) bella same loc; Agnostics desidera- 



. Salem, Washington Co., N. Y.; Jlicrodiscus helena, Manuel's 

 Brook ; Olenellus BrOggeri, Eastern Newfoundland, and perhaps 

 Shropshire, England ; Avalonia (new genus) Manualensis, a trilo- 

 bite, Manuel's Brook; Zacanthoides Eaton i, Washington Co., N. 

 Y.; Solenopleura Harvey i, Manuel's Brook; S. Howleyi, same loc. 



5. A Lingula with a cast of its peduncle has been described 

 by C. D. Walcott in the Proceedings of the U. S. National 

 Museum for 1888 (p. 480). The species is the L. cequalis of 

 Hall ;. its locality, the upper part of the Lorraine shales near 

 Rome, N. Y. Mr. Walcott refers to Davidson's description of a 

 similar case in the Eichwaldia subtrigonalis from the Black 

 River limestone in Canada, and of a similar specimen of 

 Lingula t Lesueuri. 



6. Cambrian fossils in the Salt Mange, India ; by Dr. A. 

 Warth. — Dr. Warth reports the discovery of a (Jonocephalites 

 resembling C. fornwsus Hartt, of the St. John's group, and 

 probably an Oleuus, in the " Neobolus beds." It indicates a 

 great unconformity in the Salt Range ; the beds above the 

 plane of unconformability are Upper Carboniferous and Permian. 



7. Wulfenite from Sing Sing, N. Y. — Specimens of vvulfenite 

 from Sing Sing, N. Y. have recently been received by the editors 

 from Mr. Ernest Scbernikow of New York City. It occurs in 

 small red tetragonal crystals of thick tabular habit ; the form 

 and blowpipe characters are both characteristic of the species. 

 The crystals are implanted upon a mammillary variety of green 

 pyromorphite, which forms a thin coating upon a friable crys- 

 talline limestone. A reddish mammillary mineral very sparingly 

 associated with the pyromorphite has proved to be vanadinite. 



8. Rutile- Edisonite. — Miigge has recently described some pe- 

 culiar forms of rutile from the Ural and from Snarum. They 

 show cleavage parallel to the two square prisms and in addition 



a parting in a direction nearly parallel to faces of the form - -i 



(002) ; the observed angle between two faces (over 100) was 36° 

 51' to 37° 47', while for rutile we have 902 A 90^ = 38° 4'. In con.
