[10] Specimens from Monterey, and one from the beach of the Farallone Islands, are intermediate between that described by Mr. Carpenter (Catalina Island specimen) and the northern _M. pupilla_. J. G.

Dr. Cooper stated that he had lately learned from Mr. Gill, of the Smithsonian Museum, that the genus AYRESIA, lately described in these Proceedings, is identical with CHROMIS, of Cuvier, though not _Chromis_ of Richardson, with which Dr. C. had compared it. The name of the fish must therefore be changed to CHROMIS PUNCTIPINNIS, Cooper. Col. Ransom presented, on behalf of Mr. John Wilson of this city, some Indian relics, from the State of Chihuahua, Mexico, accompanied by a letter of which the following is an abstract: The relics consist of part of a foot and hair from different mummies, a string of beads made of bone, with a few of blue stone, also part of a belt and tassel, and a piece of very strong cloth of vegetable material. These were found by Mr. Wilson in a cave situated on the western slope of a very high mountain of the Sierra Madre, which seems almost to hang over the ancient Pueblo of Chiricahui—a name signifying the Mountain of Bones. This Pueblo was occupied by the Spaniards soon after the conquest by Cortez; and from previous traditions it is supposed by the inhabitants that this cave, and another on the opposite side of the valley, had been used as a place of burial by the natives for several hundred years. It is supposed that no bodies have been deposited there for the past hundred and fifty years, and perhaps longer.
