Many of the specimens from which the preceding description was made conformed to authoritative descriptions and figures of the wellknown T. Jiavescens (more properly termed ntger), of Europe, and also agreed with eight examples of the species given me by Dr. Schaffer. Most of the Harriman specimens varied greatly, however, in the characters of accepted specific value--for example, those of the claws and dental spines. These variations, bearing importantly upon the interrelations of three members of the genus, are tabulated below. Tullberg's (1872, pp. 36-37, taf. 5, figs. 1-6) diagnosis of T. Jiavescens is, "Antennae corpore non longiores. Spinae dentium simplices 78, intima magna. Unguiculus superior dentibus 2 instructus, inferior lanceolatus. Long. 4 millim." Tullberg adds that the inferior claws are unidentate. With this description compare the following records. The figures after the + signs refer to the number of large spines beside each dental scale. Excepting these variations, all the individuals are essentially alike and nearly all the variations given are found in one lot of specimens (No. 63, Muir Glacier), among which are also the forms arcticus and americanus. Individuals of class No. 1 are clearly niger Jlavescens). Those of No. 2 depart from the type in having an extra tooth but are more typical than No. 1 by having but one accessory spine. Having admitted No. 2 as niger, how may we exclude No. 3, as regards the claws? The number of spines is normal on the left, and but one too many on the right dens. Considering the numerical variability of the spines, No. 3 could still be called niger. Notice, however, that No. 3 is just as evidently a variety of T. ...
