THE FOSSIL STALK-EYED CRUSTACEA 93 



ascribes the genus to the Cretaceous but apparently without suffi- 

 cient grounds ; Bittner, 1875/° and Schliiter, 1879,*^ note that Palaeo- 

 corystes laevis of the Cretaceous is related to Raninoides, but do 

 not place it in that genus. 



KANINOIDES VADERENSIS, new species 

 Plate 22, fig. 5 



Desc7'iption. — Carapace very convex from side to side, gently so 

 from front to back. Surface smooth and glossy to the naked eye, 

 punctate, the punctae larger and crowded on the anterior two-fifths, 

 becoming smaller and less crowded posteriori}^ almost to disappear- 

 ance; however, everywhere there are widely scattered punctae of a 

 larger size. Submedian grooves shallow; the outline of the cara- 

 pace save for the spines is nearly oval. Lateral margin marked by 



I a row of fine bead graniiles. Just below a band of larger granules. 

 Antero-lateral spine narrow, projecting forward more than out- 

 ward ; the tips are broken off. Outer orbital spine narrow, acute, 

 separated by a broad, shallow sinus from a much shorter spine ; this 

 in turn is separated by a deep U-shaped sinus from a broad, flattened, 

 subacute spine. A narrower sinus lies between it and a much smaller 

 spine ; between this and the rostrum there is a broad arcuate margin. 

 Rostrum with slightly convex, granulate margins and a median 

 ridge. 



I A portion of the merus of the left cheliped is nearly circular in 



■ cross-section, and the surface fineh^ rugose, A.t a short distance is 

 an impression of what appears to be part of the manus ornamented 

 with a reticulated pattern of fine granules. 



Measw^ements. — Length of carapace of holotype 33 mm.; greatest 



' width of carapace near the middle 18.4 mm. ; width at posterior base 

 of antero-lateral spines 1G.8 nmi.; length of rostrum 2.6 mm.; fronto- 

 orbital width 11.8 mm. 



Occurrence. — ^^^''ashington : 1 mile west of junction of Olequa and 

 Stillwater Creeks on the latter near Vader, Lewis County, in section 

 30, township 11 north, range 2 west; upper Eocene series, Tejon 

 formation. One specimen showing dorsal surface of carapace and 



I two fragments of appendages. Holotype in University of Wash- 



j ington. 



i Oregon : "Western part, at "• Basket Point " on L^mpqua River, 12 

 miles below mouth of Calapooia River, Douglas County; middle 

 Eocene series. One small specimen about 16 mm. long, with a por- 

 tion of the carapace exposed, showing posterior and one lateral 



i margin with antero-lateral spine. Cat. No. 353355, LT.S.N.M.
