. Text-fig. 57. Molgula malvinensis Arnback (St. 159): A, specimen removed from test; B, oral tentacle; C, dorsal tubercle, with ganglion and neural gland; D, part of branchial wall. Remarks. As pointed out by van Name (1945) this species resembles M. occidentalis Traustedt. It is even more like M. pyriformis Herdman. From these two species it can be distinguished as shown in Table 36. M. pyriformis rests on a single specimen and as the differences separating it from M. malvinensis are not great it might be possible to unite it with that species if more specimens could be examined from the are

M. pyriformis rests on a single specimen and as the differences separating it from M. malvinensis are not great it might be possible to unite it with that species if more specimens could be examined from the area from which the type of M. pyriformis was obtained. In the meantime, however, the two species must be recognized. Distribution. Antarctic (South Georgia, Shag Rocks; Kerguelen), Subantarctic (Falkland Islands; Macquarie Island).
