vol. 2, pt. 2.] A TAXONOMIC STUDY OF THE SALPIDAE METCALP. 171 



Traustedtia multiientaculata is a very rare species, first reported by 

 Quoy and Gaimard (1 826-1834) from the East Indies (New Ireland). 

 It has since been reported from the southern Brazilian coast (Trau- 

 stedt, 1893), from south of the Equator off the west coast of Africa 

 (Dober, 1912), from the north Atlantic Ocean near Madeira (Apstein, 

 1906, b) and near the Azores (Apstein, 1894, b), and again from the 

 East Indies (Amboina, by Apstein, 1904). 



Traustedtia multitentaculata, subspecies bicristata, is represented 

 by a single specimen of the solitary form from the north Atlantic 

 Ocean, off the New England coast. 



Traustedtia radiata, another very rare species, was first reported by 

 Apstein (1906, b) from the eastern and western Indian Ocean (Tiefsee 

 Expedition, station 182, north of Cocos Island, and station 235, north 

 of Madagascar). This species is not represented in our collections. 

 Its validity as a species is doubtful, pending the reexamination of the 

 material. 



UNIDENTIFIABLE SPECIES OF SALPIDAE AND SPECIES OF DOUBTFUL VALIDITY. 



Unidentifiable species of Salpidse and species of doubtful validity 

 are named below alphabetically with a word of comment. In the 

 preparation of this list I am much indebted to Traustedt's (1885) de- 

 tailed bibliographic studies. Identified species are named in the 

 synonomy lists under each species. 



Biphora depressa Sars, 1829, is said by Traustedt (1885) to be S./usiformis. I have 



not succeeded in finding in this country this paper of Sars's. 

 Eolothuria denudata Linnaeus, 1758 [=Browne's (1756) Thalia no. 3]. 

 Pterolyra beroides Lesson, 1832, not a salpa. 

 Salpa amphoraeformis Lesson, 1832, apparently not a salpa. 

 5. antarctica Meyen, 1832, can not be identified. 

 S. antheliphora Peron and Lesueur, 1807, (antheliophora, Meyen, 1832) can not 



be identified. 

 S. bicornis Ciiamisso, 1819, can not be identified. 

 S. biennis de Blainville, 1827, may have been Ritteria hexagona. 

 S. bipartita Bory de St. Vincent, 1804, not a salpa. 

 S. clostra Milne-Edwards, quoted by Cuvier (1828), is said by Traustedt (1885) 



to be S.fusiformis. I have not found Milne-Edwards' reference to this species. 

 5. cyanea Delle Chiaje, 1828, may have been Cyclosalpa pinnata. 

 S. cyanogaster Peron, 1807, Traustedt thinks this may have been Thalia demo- 



cratica. I do not see that it can be identified. 

 S. qimbiola Dall, 1872, apparently 5. fusiformis, aggregated zooid. This is 



indicated both by the published description and by the unpublished drawings 



which Dr. Dall has kindly shown me. 

 5. dolium Quoy and Gaimard, 1826-1834, can not be identified with certainty. 



It may have been Pegea covfederata. 

 S. dubia Chamisso, 1819, probably S. africnna, aggregated zooid. 

 S. dubia Lesson, 1832, apparently not a salpa. 

 S. elongata Quoy and Gaimard, reference in de Blainville (1827), is said by 



Traustedt (1885) to be 5. cylindrica. I have not found Quoy and Gaimard 's
