with them, no important changes have transpired since Paleozoic 

 time ; while at the same time, our perplexity regarding the proper 

 relation of Paleozoic insects to modern types is often very great. 



6. Footprints on the Triassic Sandstone {Jura-Trias) of New 

 Jersey. — Mr. John Etebkan reports to the Editors (Sept. 10), 

 by the gift of a fine photograph, the discovery of foot-prints, re- 

 lated to Anomoepus major of Hitchcock in size and characters — 

 from near Milford, Hunterdon County, New Jersey. On the 

 larger slab the fore-foot is 4-toed and 6 inches long and broad ; 

 the hind-foot is 3-toed and 12 inches long. On a smaller slab 

 on which there is one track only, that of the fore-foot, there are 

 five toes, and the length is 1\ inches. The specimens are now in 

 the Geological Museum of Lafayette College. 



1. Cervus Americanus Harlan, from shell-marl beneath a bog 

 in Warren Co., New Jersey. — This species was founded on a few 

 bones from Big-Bone Lick, Kentucky (Proc. Philacl. Amer. Phil. 

 Soc, 1818, 376). The Fourth Annual Report (June 1885) of the 



E. M. Museum of Geology and Archaeology of Princeton, con- 

 tains a plate representing a fine skeleton from the above-men- 

 tioned locality now in the museum. Professor Scott institutes for 

 it the new genus Cervalces. The skeleton fails only in five caudal 

 vertebrae, 1 scapula, 1 humerus, 1 calcaneum, 2 ribs, 3 carpals, 

 1 phalanx, and some of the sesamoids. 



8. Pteropod of the St. John Group). (From a letter by Mr. G. 



F. Matthew, dated St. John, New Brunswick, Dec. 8.) — I have 

 received a letter from Mr. Ottomar Novak, of Prague, in answer 

 to one giving him a description and figures of the new genus of 

 Hyolithoid Pteropod of the St. John group (Cambrian), described 

 in this Journal, October, 1885, page 205, under the name of Diplo- 

 theca. 



He informs me that Phragmotheca of Barrande, to which I had 

 compared it, may be described as " a Hyolithes having a triang- 

 ular section, and on each side a great dilation of the testa;" and 

 that Barrande's figure " represents only the apical end of the 

 whole sheath, the opposite end bearing the opening being un- 

 known." This being the case, the known portion of Phrag- 

 motheca corresponds to the septate portion of the sheath of 

 Diplotheca, and not to the whole sheath (including the lateral 

 phragmated portion). It follows, as Mr. Novak has remarked, 

 that there is no special relation between the two genera. 



I may add that the upper dotted line of the fig. 3b, page 294, 

 giving the section of Phragmotheca, is erroneous as regards the 

 dotted line connecting the wings, there being no enclosed space 

 at the side of the sheath. The lateral partition and diaphragms 

 of Diplotheca are therefore features which distinguish it from 

 other Hyolithoid shells.
