Scudder describes seven specimens, all males, Nos. 1226 (now 



No. 63), 1447 (now No. 94), 3860 (now No. 95), 6600 (now No. 



96), 8635 (now No. 98) and its reverse 8533 (now No. 97), 



14982 (now No. 99) and 8689, all in the Collection of the Museum 



of Comparative Zoology of Harvard University. Of these 



Figure 28. — Tcthncus licnfcii Scudder. Specimen No. 8635 (98). Legs: 

 a, first right ; b, second right ; c, third right, x 10. 



I have seen only specimen No. 8689. Scudder's description and 

 measurements are correct. The best preserved specimen is that 

 which is now numbered 97 and 98. Ovir text figure 28 shows the 

 arrangement of spines on the first, second and third legs. The 

 fourth leg does not possess as many spines, but as it is less per- 

 fectly preserved I refrain from giving a drawing of it. The legs 

 are complete and show the claws. Only one claw however is 

 really perfectly preserved. It is an upper claw of the first left 

 leg of specimen No. 98 and is reproduced in our textfigure 2q at 

 a magnification of 440 diameters as drawn with the aid of an 

 Abbe drawing apparatus. 



Scudder's description of the species and his measurements are 

 correct and I have nothing more to add to them.
