discussion
Remarks The specimen examined has a mid-dorsal tooth on pereionite 6 in addition to the usual teeth on pereionite 7 and pleonites 1 – 3. Otherwise, it looks very similar to Alexandrella pulchra. Only minor differences in the form of coxae 1 and 4 were observed. The shape of the eye is similar to that of A. pulchra, but the body and leg pigmentation is less pronounced. A small tooth is also present in the specimen from the continental shelf of the Ross Sea illustrated by Holman & Watling (1983) and a specimen from the eastern Weddell Sea illustrated by Rauschert & Arntz (2015). The latter specimen has much smaller eyes than A. pulchra, and according to an early draft of Rauschert & Arntz’s book, it was collected during the cruise ANT-XXI (obviously ANT-XXI / 2), which almost exclusively sampled on the continental shelf.
