 ment on Pj and P., L= I'/s br. P^ 12 — 18; 4,.-. mm. Distal piiinulars 

 (on the distal p) L = 3 — 3'/2 X br. Disk 2 mm. 



Sp. 8 (St. 47). The eirrals a little shorter (L = 1 ' 2 — l'Vé br).

From St. 45 and 53 there are 2 very small specimens with very 

 serrate arm-bases. Sp. 6 (St. 45) presents a transition form to these 

 ones and shows that they are young forms of the above-described
