. Discovery reports. Discovery (Ship); Scientific expeditions. OPHELIIDAE 167 Benham attaches some importance to the shape and length in relation to number of segments in his specimens. I cannot follow him here: the examples before me vary in shape from that of a cigar to that of an acorn. I have examined Mcintosh's three co-types, and they vary considerably in their degree of papillation, the most extreme example being serrated rather than strongly papillated. In my view all the intermediate stages between a faint areolation to large papillae are present in this species. To summarise my remarks, I suggest that T. olens should be provisionally separated from T. kerguelensis, on the ground that T. olens has 29 to 31 segments and T. ker- guelensis 23 to 27; that T. olens has 15 to 16 segments involved in the posterior division of the body and T. kerguelensis 10 to 11; and that in T. olens the body passes gradually into the anal cylinder which is equal in length to the last two segments, whereas in T. kerguelensis the anal cylinder, which is equal in length to the last four segments, comes off more abruptly from the body. Moreover, the terminal segments in T. olens are smooth and in T. kerguelensis more or less laciniated or papillated. Ehlers regards T. olens as identical with the European T. forbesii. The latter species seems to me to be nearer to T. kerguelensis than to T. olens. Fauvel gives 23 to 26 for the number of segments of T. forbesii. I have also observed that the longitudinal furrows of the anal cylinder are fewer and the areas they delimit larger than in T. kerguelensis.
