SCHIZOPODS, VOCALLY SKIZOPODS 257 
Dunedin, New Zealand, has informed me by letter that 
among specimens which he collected in Tasmania during 
January, 1892, ‘one is especially interesting, a freshwater 
Schizopod from the very summit of Mount Wellington, 
that is, from a height of 4,000 feet, and that this crus- 
tacean is quite unique, and will require a new family all 
to itself.’ Writing again, he tells me that the animal has 
no carapace, but is divided lhke an amphipod, so that he 
has named the genus Anaspis, which means ‘ without a 
shield.’ From the available informatior, therefore, it is not 
difficult to predict that the number of Schizopod families 
will in the near future be augmented from four to six. 
Family 1.—Lophogastride. 
The carapace is rather large, more or less calcareous, 
loosely covering more or less of the trunk, the segments 
of which are well defined dorsally. The first maxillipeds 
are robust, with exopod imperfectly developed or wanting, 
the epipod very large and projecting within the branchial 
cavity. The second maxillipeds have the terminal joint 
obtuse. The six following pairs of appendages are uniform 
and ambulatory, with well-marked finger. The branchize 
are arthrobranchiz, very complex, arborescent, consisting 
of three or four principal branches, the innermost largest 
and freely projecting beneath the trunk, and of others 
covered by the carapace; the hindmost pair are rudi- 
mentary or wanting. ‘The marsupium or maternal pouch 
consists of seven pairs of plates. The pleopods are well 
developed in both sexes, uniform, natatory. ‘The develop- 
ment is without any free metamorphosis. 
G. O. Sars, from whose exceedingly valuable report on 
the Challenger Schizopods this definition is adapted, allots 
four genera to this family. 
Lophogaster, Michael Sars, 1856, still possesses but a 
single species, Lophogaster typicus, M. Sars, which at 
present is only known from the North Atlantic and the 
South Atlantic, without having been discovered in inter- 
mediate positions. It is recorded by Canon Norman from 
the Shetiand Isles. Its sculptured carapace has a short
