GENERA AND FAMILIES OF THE CHIMA€ROIDS. 
BY SAMUEL GARMAN, 
THIS note is an abstract from the Bulletin of the Museum of 
Comparative Zoology, preliminary to the more extended discussion 
now in press, with illustrations of the form, anatomy and kindred, 
of a specimen purchased, March, 1900, in Japan by Dr. Alex. 
Agassiz from a dealer who pronounced it specifically identical 
with Harriotta pacifica Mits., having, as understood, had an identi- 
fication by Professor Mitsukuri or a comparison with the type. 
On its arrival it was recognized at once to be a representative of 
a new genus and not to belong to Harritta. Whether it was of 
the mentioned species could not have been determined from the 
original description and figure. Externally the individual here 
serving as the type of the new genus Rhinochimera bears some 
resemblance to the types of Harriotta raleighana G. B., but on 
closer examination it is seen to possess radical differences in 
structure. The teeth of RAinochimera are of a much less differ- 
entiated form than those of any other of the recent genera of the 
group; that is their later stages are more like the earlier, and 
presumably more like the teeth of primitive chimzroids; they 
approach those of the extinct myriacanths and the very early 
conditions of the teeth of other living chimeroids, Chimera, Cal-
