Announcement has just been made of the recent return of a Harvard-Yale expedition from the Bahamas, where they were pursuing a small guinea-pig-like redent. The expedition was headed by Dr. Thomas Barbour, director of the muscum of comparative zoology and professor of zoology. He was accompanied by his family and by Mr. and Mrs. J. C. Greenway of the museum staff; Mr. Froelich Rainey of Yale was the archeologist.

Unhappily no evidence of the redout was found, although many other important discoveries were made. It was assumed, because of the apparent devastation and the piles of rocks thrown up by the sea, that the whole species was exterminated by the hurricane of October, 1928.

Large collections of reptiles, land shells, and insects were obtained with the aid of the natives, and among the specimens obtained a number of new species has already been found.

The mouster skull and jaws of a new type of triple-horned dinesaur, a giant four-legged and dragon-tailed reptile which grated in the lewlands of castern Wyeming more than sixty millien years ago, will be placed on exhibit at the Museum of Comparative Zoology at Harvard this week. The skull is 5 feet long and 4 1-2 feet wide, and was mounted in life on a dinosaur about eighteen feet long and ten feet high.

Discovery of this rare and important specimen, which has an unusually wide head, was made in Wyeming in 1930 by Erich M. Schlaikjer on field research for the museum, but has not been made public until now.

This dinosaur, known as Triceratops eurycephalus (wide-head), represents the last recorded surviver of that great grump known as the Certopstaus.

All known individuals of Triceratops are from North American and eastern Asiatic deposits, and lived in the last Cretaceous period, sixty million to 105 million years ago. The head of a Triceratops has a great frill of bone spreading out over the neck from the skull proper, like a collar, and acting as protection against the carnivorous animals which lived in that period. They once roamed the eastern uplift of the Rocky Mountains from Alberis to New mexico in great members and many skeletal remains have been found.
