In order to avoid confusion I must therefore, at least provisionally, establish T. distinguenda as a separate species ; when more material has been examined the question can be reconsidered. 7. Thysanopoda lateralis, n. sp. (Figs. 14-16). Description. — The carapace has no marginal denticles, but above its latéral border a fine ridge runs from the anterior nearly to the posterior end, and this ridge is the upper limit for a linear impression of a certain breadth ; in this way a rim of the carapace is sharply marked off from the remainder ; the rim itself is narrow in front, considerably broader behind the.

A gastro-hepatic groove is wanting. The front part of the carapace is considerably produced, seen from above almost covering the eye-stalks ; the end itself is produced into a com- pressée! curved acute rostrum, the proximal half of which is directed obliquely upwards and forwards, while the distal part is horizontal ; the upper side of the front part of the carapace.
