Occurrence. — Oregon: Springfield Junction, 1 mile west of 

 Springfield, Lane County ; Oligocene series ; three specimens and one 

 impression of parts of the carapace; also two specimens showing 

 together the episternum and the first three sternal somites. Cat. No. 

 353340, U.S.N.M. 



Oregon: Western part, one-fourth mile west of Springfield Junc- 

 tion, Southern Pacific Railroad, Lane County; Oligocene series. 

 Six specimens, more or less defective, showing the dorsal side of 

 the carapace and in one case, three segments of the sternum. The 

 largest one which has also some pieces of the chelipeds is made the 

 ]iolotype; Cat. No. 353339, U.S.N.M. 



Oregon: Near Eugene; upper Oligocene series; three specimens 

 and two impressions of carapace, also fragments of sternum and 

 appendages. The largest carapace is finely granulate and dull all 

 over, but does not retain the true outer surface which is shining and 

 l^artly smooth. 



KANINOmES ASPER, new species 



Plate 23, fig. 5 



Description. — This species differs from all those aboye described in 

 the ornamentation of the surface and in the character of the antero- 

 lateral spine. In the small type-specimen, which is brown in color, 

 the surface is roughened with fine single scabrous granules without 

 large punctae interspersed as in fulgidus. The antero-lateral spine is 

 directed more outward than forward and the margins on either side 

 curve rapidly away from the spine so that the sinuses formed are 

 very broad and shallow, not at all angular, as they are in americana. 



A fragment of carapace showing the posterior left corner is nearly 

 black; it belonged to a larger specimen than the type but has the 

 same asperities besides a posterior and postero-lateral rim of very 

 fine granules. 



A third specimen exposes a part of the merus and carpus of the 

 right cheliped. Most of the outer surface layer is lacking, but there 

 are indications of fine rugose lines. The merus is strongly curved 

 and very stout. 



A fourth specimen contains several small fragments of carapace 

 crushed together with no means of identification except the charac- 

 teristic surface. 



Occurrence. — Oregon: Western part, at Springfield Junction, one 

 mile west of Springfield, Lane County ; Oligocene series. Four frag- 

 ments of carapace and appendages ; the fragment showing the antero- 

 lateral spine and adjacent part of the carapace may be considered the 

 type; Cat. No. 353337, U.S.N.M.
