THE FOSSIL STALK-EYED CRUSTACEA 109 



CALLIANASSA KEWANA, new species 



Plate 25, figs. 5-7 



Description.— Yroximal end of manus (pi. 25, fig. 5) nearly at 

 right angles to lower margin, upper margin convex and converging 

 toward lower margin at distal end. Outer surface very convex 

 between the acute upper and lower margins, immovable finger bent 

 strongly inward (pi. 25, fig. 7). Inner surface in great part convex 

 both longitudinallv and transversely, except above the lower edge 

 where there is an elongate hollow leading back from the finger (pi. 

 25, fig. 6). Just below upper margin and just above lower margin 

 on outer surface a row of about 12 sockets. Lower margin bluntly 

 serrated, a small socket in each interval. On the outer surface are 

 several scattered punctae not far above the lower margin, also a few 

 (four) at distal end behind and above the sinus. On the inner 

 surface are two sockets obliquely placed behind the sinus. 



Measurements.— Kight manus, holotype, length measured from 

 sinus between fingers 15.3 mm., width near proximal end 17.5 mm., 

 width at distal end 15.7 mm., greatest thiclmess 8.4 mm. 



Oceurrence.—C'^irdorniii : Carrizo Creek, Alverson Canyon, Coyote 

 Mountain, Imperial County; Pliocene series; five specimens of 

 manus, two right, three left, two having the base of the fixed finger 

 attached. Holotype in University of Cahfornia. 



CALLIANASSA FRESNOENSIS. new species 



Plate 2G, figs. 4 and 5 



Descnption.—Vpvev and lower margins thick, bluntly rounded 

 (pi 26 fi^ 4) ; upper margin straight, lower margin sinuous, prox- 

 imal margin oblique to upper (pi. 26, fig. 5). Inner and outer sur- 

 faces equally convex, the convexity rather uniform from one end to 

 the other Margins marked with two rows of punctae or hair sock- 

 ets; one row is along middle of upper margin, the other on the outer 

 surface; rows irregular, in the main nearer together than are the 

 individual sockets in each row. Six sockets are visible in each row 

 above. On the lower margin the rows are nearer together, one row 

 along the middle, the other toward the inner surface. Both inner 

 and outer surfaces have a number of distant punctae; on lower halt 

 of inner surface they form two rows of five each. 



Measit.renients.—A]pi:>TOximiite length of manus through middle 12 

 mm., greatest width, toward proximal end, 7.3 mm., width at distal 

 end 7 mm., thiclmess 4.5 mm., greatest diameter of fixed finger near 



its origin 2 mm. r^■^ r^- -r 



Occurren^^e.—Caliiorma: 1 mile southeast of Oil City, i^resno 

 County; Eocene series (called Tejon by Arnold); one specimen of 

 the left manus, holotype, in California Academy of Sciences.
