numerous. Tlie punctae on the lower and distal part of the inner 

 surface of the propodus are similar to those of the outer surface. 



Minor chela (pi. 28, figs. 2 and 5) narrower than major chela at 

 the distal end of the manus, its lower margin curving gradually up- 

 ward from the middle of the palm; the finger itself is longer and 

 more horizontal than in the major chela ; if it turns upward at all it 

 must be at the extreme end which is not visible in paratypes h and e. 



Measurements. — Left manus, holotype, length measured from up- 

 per base of finger 10.8 mm., greatest height 8.8 mm. Right manus 

 (paratype c) length measured from upper base of finger 12 mm., 

 length of fixed finger measured from same point 6.3 mm,, gi-eatest 

 height of manus 9,3 mm. Right manus (paratype e), length 13.4 

 mm,, greatest height 10.3 mm. 



Occurrence. — Washington: Restoration Point, Bainbridge Island, 

 Kitsap County; upper Oligocene series; one right manus (paratype 

 e) with immovable finger of a female, probably, embedded in a 

 nodule, outer surface exposed. 



Washington : Near Porter, section 22, township 17 north, range 5 

 west ; middle Oligocene series ; left manus of female with immovable 

 finger (paratype /) embedded in a nodule, inner surface exposed. 



Washington: Shaly sandstone bluff on Chehalis River below 

 Porter ; middle Oligocene series. Three specimens of the left manus, 

 two having the propodal finger attached but lacking the tip. The 

 specimen without finger (paratype a) is separate from the matrix 

 and shows inner and outer surfaces, the others show only the outer 

 surface; the larger of these is considered the holotype; the smaller 

 appears to be a minor chela (paratype h). Holotype in Stanford 

 University. 



Oregon: Sandy shale cut along the Corvallis and Eastern Rail- 

 way between Rocky Point and Oysterville, Yaquina Bay ; Oligocene 

 series. A single nodule containing two specimens of propodus, one 

 (paratype d) showing the inner surface of a right major propodus 

 complete and the other (paratype c) the outer surface of a left major 

 propodus incomplete. 



Oregon : Shale sea cliffs south of mouth of Five Mile Creek, Ban- 

 don ; lower ( ? ) Oligocene series ; left manus of male with immovable 

 finger (paratype (7), partially embedded in a nodule, inner surface 

 exposed. 



Relation. — In the shape and denticulation of the lower margin of 

 the manus, this species is akin to G . oregonensis from the Miocene 

 of Oregon, but the latter has a straight propodal finger and the two 

 fingers are nearer together at their origins instead of separated by a 

 broad lobe.
