Pliocene Ostracoda,

Brady and Robertson,* in general outline, although our specimen is 

 less regular in shape, having a sinuosity on the dorsal edge a little 

 in front of the middle, whilst the ventral edge is more or less flexed 

 along its length. The carapace also is greatly compressed as com- 

 pared with the above-mentioned variety. The carapace is highest 

 just behind the middle. Length, one-fifteenth of an inch ; height, 

 one-twenty-seventh of an inch. 



One specimen was found at locality No. 589, Wildcat Canon. 



Candona lactea, Baird, var. acuminata, nov., plate 3, figs. 20-22. 



This variety differs from recent specimens of the type form in 

 having a distinctly acuminate front to the carapace. Otherwise it 

 appears in its lateral aspect to agree with the figures given under 

 the name of C. detecta,\ but latterly referred to the species ,C. 

 lactca.% Length, one-twenty-fifth inch ; height, one-forty-second 

 inch. 



C. lactea, var. acuminata, is very rare at locality No. 585, Wild- 

 cat Canon, opposite the Caves ; at locality No. 26, San Pablo Ridge, 

 it is frequent ; and at No. 297, Bollinger Canon, it is rare. 

 Candona gracilis, sp. nov., plate 3, figs. 23-25. 



Shell in lateral aspect long elliptical, rounded at both ends. 

 Dorsal border well arched, ventral border slightly incurved. The 

 edge view shows that the carapace is fullest in front of the posterior 

 third, and that both ends are acuminate. Length, one-thirty-eighth 

 of an inch ; height, one one hundred and fifteenth of an inch. 



Among the elongate forms of Candona there are none so regu- 

 larly elongate as the above, but of the attenuate and fabiform 

 examples, C. acuminata (Fischer)§ may be especially mentioned. 



The above species was found at locality No. 589, Wildcat Canon.
