radius seems to possess two or more very small tetragonal plates 

 lying between but not belonging to the enlarged pinnules from IIBrj ; 

 it should perhaps have been chosen to represent posterior IR. Owing 

 to the condition of uncertainty I have refrained from completing 

 the diagram and have made the left hand interradius of figure I 

 [pi. 3] the vertical one in figure 4 of this text. 



I am one of a host whom Prof. C. E. Beecher placed under lasting 

 obligation through his kindly given and generous help. This speci- 

 men was found soon after his visit to my camp in the summer of 

 1903 and T name it after him, not alone in recognition of the eminent 

 position he attained in the science to which he gave his life's labor, 

 but also as a token of personal affection and in appreciation of many 

 rare mental qualities which I came to see as one can best see such 

 things through the freedom of field work by day and at the open 

 camp fire by night.

Description. Cup small; its hight measured from proxima^ 

 surface of basals to distal angle of first secundibrach 7.5mm; its 

 diameter measured from upper edge of right posterior primaxil 

 about 9.6mm ; that of its base across lower shoulders of basals 

 4mm; that of proximal ring of stem 3.3mm; sides of cup from 

 lower edge of basals to top of radials rather straight and 

 from this point gradually curving to give a somewhat ver- 

 tical edge to cup at IIBj. The more or less narrow depressed 

 margin of the plates is ornamented by numerous fine radiating lines 

 which cross the sutures ; a single large proximal interbrachial pos- 

 sesses more than 40 of these lines, and under a low power they are 

 seen to be rows of fine tubercles ; from the inner edge of this border 

 the plates rise rather abruptly to the hight of about .5mm and 

 become smooth or microscopically granular with a large flat or 

 slightly concave area which shows, near its outline, a marked ten- 

 dency toward suppression of the plate angles. The infrabasals are 

 small and ahnost completely covered by the proximal ring of the
