CALLIANASSA BANDONENSIS, new species 



Plate 27. figs. 5-8 



Holotype. — Upper margin straight, proximal angle rather promi- 

 nent, rounded; lower margin slightly arcuate, proximal angle 

 rounded, much less prominent than upper angle ; proximal end there- 

 fore oblique; distal margin vertical. Outer surface (pi, 27, fig, 6) 

 moderately convex from top to bottom and equally so in upper and 

 loAver halves ; nearly level in the opposite direction except toward the 

 ends; a deep vertical gutter just Avithin the distal margin. Behind 

 this gutter a curved tow of six small tubercles ; a similar row of six 

 tubercles at the other end; between the rows are a number of scat- 

 tered tubercles of more or less prominence, 12 being most elevated. 

 Inner surface (pi. 27, fig, 5) a little flatter than outer, with a distal 

 gutter corresponding to that on the outer surface ; behind the gutter 

 a few low, inconspicuous tubercles. Fingers lacking, but a cross 

 section of the propodus at base of fixed finger shows that it occupies 

 .about two-fifths the height of distal end of manus. 



Paratype a. — The manus (pi. 27, fig. 8) is a little longer relative 

 to its height and perhaps represents a female. The lower margin 

 does not show the arching of the male but is nearly horizontal and 

 slightly sinuous, the finger being inclined somewhat downward, and 

 regularly tapering but incomplete. Lower edge of palm and finger 

 serrate, outer surface of palm covered with distant granules, a row 

 of granules just above middle of finger, 



Paratype h. — A larger specimen (pi. 27, fig. 7) than any other, 

 showing a much bruised palm and a finger which had been broken 

 off at its base and turned over toward the outside so that its oblique 

 upper surface looks like part of the outer surface, from which it is 

 separated by a distinct angular edge. The finger lacks a tip but 

 even without it appears unusually long. Enough of the upper mar- 

 gin of the palm remains to show that it is irregularly dentate; the 

 distal outer furrow is less marked than in smaller specimens. 



Measurements. — Right manus, holotype, length measured from 

 between fingers 10.5 mm., greatest height 12.3 mm., least or distal 

 height (approximately) 10.5 mm., thickness 4.7 mm. Left propodus 

 including part of finger, paratype «, length measured from between 

 fingers 10.7 mm., distal height 10 mm. Paratype h, length meas- 

 ured from between fingers 12.6 mm., greatest height 13.2 mm., 

 length of propodal finger on upper margin, minus tip, 15,3 mm. 



Occurrence. — Oregon: Shale sea cliffs south of mouth of Five 

 Mile Creek, Bandon ; lower ( ? ) Oligocene series ; five specimens of 

 manus, three right and two left, free from the matrix. Two others 

 with fixed finger attached, one right and one left, embedded in hard
