that of gracilis, both differing conspicuously from the other species in this feature. 
The middle segment of the right exopod has an almost straight inner margin in 
Kiefer’s species, quite different from the condition in mermis and the accessory 
spine on the end segment of this exopod is minute in gracilis, whereas here it is 
strongly developed. The armature of the end segment of the left endopod also 
differs in these two species. In the fourth leg the terminal spine on the exopod 
is relatively more slender and less strongly armed than in gracilis and in the

second legs the spur on the end segment of the left endopod is here more robust 
than it is in gracilis, which differs further in having the two adjacent inner 
setae unmodified. In subsalaria only the first of these setae is transformed into 
a spine. In the male urosome the asymmetry of the first segment, shown by 
Kiefer for gracilis, is also found here; in both sexes the last thoracic segment and 
urosome lack the spiny armature found in gracilis.

According to Sars, who has given a full description of this genus, Smith has 
made a number of errors in his description of the type species, B. tasmanica. Thus
