umberland and Durham Deep Sea Dredging Report (1865), re- 

 presents the male fifth pair of feet as in T. ajfinis. These figures 

 were drawn from Hylton specimens, and there arc, so far as I 

 can make out, no examples of T. affinis in the gathering ; nor 

 have I been able, on further search, to find any specimens show- 

 ing the characters of my drawing. I take it, therefore, that the 

 specimen from which the drawing was made was an exceptional 

 one, and had I at the time recognized its abnormal character it 

 would not have been used ; but the same thing may have hap- 

 pened to Prof. Lilljeborg. Further, amongst the Whittlesea 

 specimens are some which have two external lateral spines on 

 the female fifth foot — a character usually found only in T. affinis. 

 The only unfailing distinctions between the two species seem to 

 be (1) the relative size of the penultimate joint of the female 

 fifth foot and its internal tooth; (2) the length of the anterior 

 antennae, and (3) the length and proportions of the caudal rami 

 and their setae. Frequently T. Clausii is tinged of a deep vinous 

 red : this I have never seen in T. affinis.
