and described ten years ago. He had recently had an opportunity of 
examining an entire skeleton. It belongs to the black fish, but differs 
specifically from its nearest ally, and seems to be almost intermediate be- 
tween the genera Globiocephalus and Grampus. The anatomical charac- 
ters separating these were given, and the name Globiocephalus brachyp- 
terus was proposed for the species. 
Professor Frazer spoke of a peculiar trap from York County. Dr.. 
Koenig, having been engaged upon the investigation of the minerals oc- 
curring at Magnet Cove, Arkansas, gave a preliminary notice of some of 
his results. 
Mr. B. Waterhouse Hawkins, having stated that he was at present em- 
ployed in rebuilding the skeleton of Hadrosaurus in the museum, Te- 
viewed the subject of the position of the so-called clavicles, referring 
specially to the opinions of Professors Leidy, Huxley, and Cope. He 
reminded the members that in 1868, when studying the remains con- 
tained in the museum, he had adopted the opinion first advanced by 
Dr. Leidy, and assigned the bones in question to the pelvic arch. Pro- 
fessor Cope, in 1867, had published his opinion that they were pubes, 
but had afterwards assigned them to the position of ischia, thus indors- 
ing the view advanced by Professor Huxley. Mr. Hawkins had already 
on at least one occasion demonstrated before the Academy that this opin- 
ion of Cope and Huxley was not supported by the necessities of the 
creature’s organization, and had advanced the opinion in 1879, and pre- 
viously, that the bones in question were really pubes, having the long 
section so placed as to support the abdominal walls, as in the crocodile 
and marsupials. Attention was called to the fact that corresponding 
bones had recently been placed by Owen in his description of Omosaurus 
as pubes, thus establishing the correctness of the position taken by Mr. 
Hawkins, with regard to them in Hadrosaurus, as far back as 1868, and 
steadily adhered to by him in spite of the authority of the eminent natu- 
ralists who up to the present time held a contrary opinion. Professor 
Cope complimented Mr. Hawkins on the results established by One 
description of Omosaurus, and further referred to the position of the bones 
under consideration.
