from the Cape region. They are now in the hands of Dr. Horn, of 
Philadelphia, who will describe the new forms at an early date. 
The land shells, some twenty-two species collected during the late 
expedition to the Cape region, contain some eight or ten new spe- 
cies, descriptions of which will soon be published by Dr. J. G. 
Cooper, who has already written upon the subject of Baja California 
land mollusks. The land and fresh water oligochzta contain anum- 
ber of new forms, which are being described by Dr. Gustav Eisen, 
in connection with other Pacific Coast oligocheta. The species 
found in the Cape region are entirely tropical, and show most rela- 
tionship with tropical Mexico and Central America. 
The fresh water crustaceans, of which many remarkable forms were 
collected in the clear waters of San Jose River, will be described by 
Walter Faxon, of Cambridge. G. E. 
NOTES ON THE CLIFF DWELLERS. 
In Southwestern Colorado and in Arizona there have recently 
- been extensive explorations of the ruins of a people now extinct, but 
probably related to the Pueblo Indians at present living in Arizona. 
The relics found in their houses indicate that they were an agricul- 
tural people, and to strengthen this belief remains of ancient reser- 
voirs and aqueducts exist on the mesas above. There, too, are 
ruins of houses and towers which were probably occupied betore de- 
fense became necessary and the people fled to the cliffs. The mesa 
ruins have usually become mounds overgrown with vegetation, but 
the cliff houses, from their sheltered position, are in a good state of 
preservation. . 
It may be interesting to record the uses they made ofsome of the 
plants of the region as well as the plants which they cultivated that 
grow there no more. | ae 
Corn, squash, and beans were the chief crops; the walnuts now 
and then discovered were probably brought from further south with 
the cotton which has been found on the pod, spun into thread, and 
woven into cloth. Undoubtedly, they had commerce with their own 
people further south, or with other tribes, for seashells have been 
found matted in the hair of the dead, salt most carefully preserved in 
balls, and for their arrow points, stones not found near by. 
The most valuable textile plant was Yucca baccata, the fruit of
