Recently Found Gastoroidcs in Indiana. — Moore, 69 
(11) Radii and ulnae present, right and left. 
(12) Femora, both perfect. 
(18) Tibiae, both perfect. 
(14) Fibulae, both present but broken loose from the tibiae 
and each lacks the upper epiphysis by which it attached to 
the larger bone. (The tibia and fibula are fused together 
along their lower third, the same as in the leg of the musk- 
rat.) 
15) Right hind foot — 
(a) Astragalus. 
(I>) The five metatarsals. 
(c) The first phalanx of the third digit. 
(10) Left hind loot— 
(") Astragalus and calcaneuni. 
(/>) The I, III, IV and V metatarsals. 
(c) The first phalanx of the third digit and the first and 
second of the fourth digit. 
Some of the parts now lacking would doubtless have been 
found had there been some one to oversee the digging who had 
experience and a sense of their value. 
IV. Of the Missing end Broken Parts. 
These, in the main, are indicated b} r the parts not already 
herein named. The gaps most to be regretted are made by 
the absence of the brain cavity and of the fore feet. As to the 
cranial region it is fortunate for science that there arc at 
least two pretty well preserved skulls known, viz: the Clyde 
skull of Wayne county, New York, and another larger one, 
now in the Smithsonian collection, from Lenawee count v, 
Michigan, presented by Dr. Kost. Of the fore feet no frag- 
ment appears wever to have been reported. In the restoration 
they are modeled after the forefeet of Castor. 
Any one who notes in detail the points of correspondence 
between the known pa its of the hind feet of Castoroides and 
the homologous parts of Castor, can hardly conclude that tin- 
fore feet of the former could he other than very similar to the 
same members of the latter. 
Numbers 4, 5, 6 and 7 of the cervical vertebrae were not 
found. 
Of the caudal vertebra^ numbers 5. 6 and 8 of the larger
