voi,. 2, ft. 2.J A TAXONOMIC STUDY OF THE SALPIDAE METCALF. 149 



Quoy and Gaimard's Salpa multitentaculata (fig. 134) seems to be 

 the same as Apstein's S. verrucosa, though their figure and description 

 are not sufficiently complete to make one entirely certain. Yet the 

 general form of the body and the position of the four pairs of "ten- 

 tacles" seem to indicate probable identity. Quoy and Gaimard's 

 description and figure are given for comparison. Quoy and Gai- 

 mard's form seems clearly a Transtedtia, and of the probably two 

 species now known it must belong to multitentaculata. It is 

 either this species or one not as yet rediscovered. The elongation of 

 the posterior "tentacles" in Quoy and Gaimard's and Apstein's 

 specimens is greater than in our form. I therefore assign Apstein's 

 specimen to the main species and our specimen to the subspecies.

Quoy and Gaimard's description is as follows: 



15. BIPHORE MULTITENTACULE. SALPA MULTITENTACULATA, NOB. 

 Planche 89, figure 19. 



Salpa, parva, cylindrica, postice longissime bicaudata, antice capillata; appendi- 

 cibus gracilibus apice tuberculosis; oribus terminalibus. 



Cette espece est une des plus singulieres que nous ayons rencontr£es, par les fila- 

 ments qu 'elle porte en avant. Elle est cylindrique, obtuse aux deux extr£mites. 

 L'ant6rieure, arrondie, a eon ouverture terminale entre deux leveres dpaisses; la 

 posterieure, un peu gibbeuse, a eglament son ouverture presqu'a la pointe portee sur 

 un petit prolongement. De la gibbosite" partent deux tres-longs filaments deli6s, 

 marques d'une ligne rouge dans toute leur 6tendue. Au-dessus de la partie anterieure 

 sont fixes six appendices filamenteux, renfl^s, pointus aleur extremity, qui est rouge, 

 lis sont presqu'aussi longs que le corps. Le nucleus est orange; le reste de I'animal, 

 blanc. Au-dessus des organes digestifs on apercoit un petit corps contourn£, qui est 

 sans doute une chaine d'oeufs.

TRAUSTEDTIA MULTITENTACULATA, aggregated form. 



Traustedt (1893) first described the aggregated form of this species 

 from specimens in the collections of the Plankton Expedition, from the
