12 The Ottawa Naturalist. [April 



during the year. In the October-November number of The 

 Ottawa Naturalist a first list of local Geometroidea was pub- 

 lished, in which 168 species were included 



The Geological Branch. 



The past year has been marked by a number of interesting 

 and important paleontological finds by amateurs, and a con- 

 siderable activity in this district by the Geological Survey. 



The most notable find of the season was made by Mr. J. E. 

 Narraway, who was so fortunate as to discover a very perfect 

 little starfish at City View. Not onlv are good star fishes verv 

 rare in themselves, but this specimen has covering plates over 

 the ambulacral grooves, a feature previously entirely unknown 

 among the free echinoderms, and shoving a connection of the 

 star fishes with the more primitive stalked echinoderms, the 

 cystids and crinoids. 



Next in importance was the discovery by Miss A. E. Wilson 

 of a number of specimens of a plicated Triplecia, in the lower 

 beds of the Utica at Dow's lake. This proved to be a new species, 

 and is of very considerable interest in its bearing upon the correla- 

 tion of the beds in which it was found with beds containing a 

 similar Triplecia in Minnesota. 



Both Messrs. W. J. Wilson and E. D. Ingall were fortunate 

 finders of entire specimens of Asaphas canadensis Chapman, 

 near the locality in which Miss Wilson found the Triplecias. 

 Entire specimens of .4. canadensis had been found at Colling- 

 wood and Oshawa, but, with the exception of a single small 

 specimen in the Stewart collection (from New Edinburgh), 

 they have not previously been found at Ottawa. Mr. Wilson 

 found several very good specimens, and Mr. Ingall's single 

 specimen was of great importance, for, being in limestone, it 

 retained the natural convexity, and showed the course of the 

 facial suture, a feature of prime importance. It is now possible 

 to show that the species really belongs to the genus Ogygites, and 

 it is, so far as known, the only American representative of that 

 French and Russian genus. 



Another interesting addition to the fauna at Ottawa was 

 made by Mr. W. A. Johnston, who, while attending the field 

 outing of the Club last spring at Mechanicsville, found a number 

 of specimens of Nanno aulema Clarke, in the Black River lime- 

 stone. Dr. Percy E. Raymond added three new species of 

 Bathyurus to the local fauna, two of them from the Pamelia 

 near W T estboro, and one from the lower part of the Trenton in 

 Eastview. 



Forthe Geological Survey. Mr E. D. Ingall and Dr. Raymond, 

 lid a considerable amount of work throughout the season, and
