MAUITA. 135 



Surface. Surface temp. 74° F. 11 January, 1905. One incomplete specimen 

 taken. 



Between the Galapagos and Paumotu Islands: Sta. 4726 (lat. 12° 30' S., 

 long. 111° 42' W.). Surface temp. 78° F. 18 January, 1905. Several fragments, 

 one exceptionally large, though lacking the head, taken at the surface. 



Between the Galapagos and Paumotu Islands: Sta. 4727 (lat. 13° S., long. 

 112° 45' W.). Surface temp. 77° F. 18 January, 1905. Fragments from 

 surface. 



Northeast of the Paumotus: Sta. 4734 (lat. 17° 36' S., long. 122° 15' W.). 

 Surface. Surface temp. 81° F. 22 January, 1905. One large and nearly com- 

 plete specimen. 



This species, originally described from the Mediterranean, where it is well 

 known, was also previously reported, by Apstein (1891), as occurring in the 

 Pacific, off the coast of Chile. The specimens above recorded seem fully to con- 

 form to the pubUshed descriptions and figures. The form from the Hawaiian 

 Islands described by Treadwell under the name fuscopunctata is probably iden- 

 tical with the present species. The specimen reported above from Sta. 4721 

 also has brown spots, but these are possibly chiefly due to preservation, while 

 some of the specimens from Sta. 2682 are distinctly brown throughout, this also 

 being due to preservation, as a specimen from the same station, but differently 

 preserved, is colorless and translucent. 



Mauita, gen. nov.^ 



Prostomium with two very large eyes projecting laterad; five tentacles, 

 an unpaired median dorsal one, and two pairs of short ones on the ventral side 

 anteriorly. 



Proboscis armed with two stout and long, non-chitinous, prehensorial proc- 

 esses which in the retracted condition of the proboscis protrude from the mouth. 



The first two somites coalesced, the others free and distinct. 



With three pairs of tentacular cirri, all ventral in position; two pairs upon 

 the first segment ( = somite I + somite II) and one pair upon the third. 



True parapodia beginning upon the fourth somite. Parapodia lateral in 

 position. All uniramous, represented by the neuropodium. Each terminated 

 by a conspicuous cirrus-like process. Cirri conspicuous, the styles foliaceous. 



A single aciculum in each parapodium, its tip free. Setae all composite, 

 slender and numerous. 



* Polynesian Maui, a mythical tiero.
