low Brook Road, where a low ridge of the rocks, covered with a thin 

 layer of bowlder till, was cut through in grading the street. The locality 

 is about half a mile farther east than we had heretofore assumed the 

 border of the Triassic formation to be, and the exposure provides us with 

 the first definite evidence which proves the presence of rocks of that age 

 east of the trap ridge, although the region has always been mapped geo- 

 logically, on theoretical grounds, as Triassic covered with recent surface 

 deposits. 



West of the trap ridge, wherever specimens were obtained in place, the 

 Triassic sandstones and shale were always found to be of the characteristic 

 red color. In this newly discovered exposure, however, the sandstones are 

 almost white and the shales are gray or black and, occasionally, in the con- 

 dition of dense hard argillite, evidently due to metamorphism effected by 

 proximit}^ to the trap ; although why this should have been effective east 

 of the ridge and not west of it is a problem for further investigation. In 

 some of the shale layers may be seen more or less fragmentary plant re- 

 mains, consisting of flattened stems and seedlike bodies. In places these 

 are quite abundantly distributed, but they are not sufficiently well defined 

 for identification. Previous mention of rocks of Triassic age on Staten 

 Island may be found in the Proceedings of the Natural Science Asso- 

 ciation OF Staten Island 2: 9. Ap. 11, 1889; ibid. 2: 17. Oct. 10, 1889;

2. A Rare Fungus Found on Staten Island. — Last autumn, while collect- 

 ing fungi indiscriminately, I found this specimen on a decayed stump near 

 Huguenot Station. It attracted my attention by reason of its bright yellow 

 color. Dr. William A. Murrill of the New York Botanical Garden iden- 

 tified it as Pholiota lutea Peck, New York State Museum, sist Annual 

 Report i: 288. 1897 [1899]. It may be found described and figured in 

 Dr. Murrill's Illustrations of Fungi — III, in Mycologia i : 84, 85, pi. 7, f. 4, 

 May, 1909, where he says : " Although separated from the European spe- 

 cies, Pholiota spectahilis by Professor Peck in 1898, it is very closely 

 related to that species and might be considered only a variety of it by some 

 authorities. Both species are considered very rare in this country." 



Doctor Hollick exhibited and commented upon a recently issued work 

 entitled " Flora of the Vicinity of New York," by Mr. Norman Taylor, and 

 stated that a suitable review would be prepared for printing in the Pro- 

 ceedings. (See this issue, p. 102.) 



Doctor Hollick read a clipping from the Yorkshire Weekly Post, Leeds, 

 England, November 7, 1914, transmitted by Mr. John De Morgan, and 

 bearing the title " An American Butterfly in England." The article is 

 intended to advance the theory that the butterfly mentioned, Danais plex- 

 ippus Linn., may be capable of trans-Atlantic migration under favorable 

 wind conditions. Dr. Davis discussed the improbabihty of this theory 

 and remarked that the species had a very wide geographic distribution,
