NO. 2 HARTMAN, BARNARD: BENTHIC FAUNA OF DEEP BASINS 99 



closely encased and the anterior end of the body is speckled with dark 

 pigment. The subspecies differs from the stem, H. tubicola (Miiller), 

 in that the bifid subacicular hooks of posterior segments have the main 

 tooth nearly straight instead of at right angles to the shaft ; the maxillary 

 jaws numbered III and IV have more numerous teeth than corresponding 

 ones in the stem (Moore, 1911, p. 281). 



This was first named from San Clemente Basin in 1038 fms, in green 

 mud, associated with hydroids, a barnacle, Scalpellum proximum Pilsbry, 

 a small stalked tunicate, and an anemone, Sagartia sp. (Moore, 1911, 

 p. 282). The specimen from the Velero Basin was associated with a 

 white holothurian and 10 other kinds of polychaetes (see Analyses in the 

 following part of this volume) .

Large individuals, agreeing with the description of the type, were 

 taken in West Cortes, East Cortes, Long and Velero Basins in depths 

 of 899 to 1285 fms. The species is known more widely south to western 

 Mexico (Hartman, 1944, p. 83).

Two specimens come from West Cortes Basin in 835 fms. The species 

 is commoner in shallower, less than 100 fm bottoms off San Diego, where 

 it is most abundant in sediments of red and brown sands (unpublished 

 records). It is more widely known from cosmopolitan areas of warmer 

 parts of the Atlantic and Pacific oceans. 



Onuphis sp. 

 Two individuals come from East Cortes Basin in 899 fms; another 

 from San Clemente Basin in 1018 fms. The longest one occupies a long, 

 about 300 mm, dark, flexible tube, which encloses an animal 126 mm 

 long. The body is attenuate and anteriorly depressed. Ventral cirri are 

 cirriform through 3 segments and thereafter padlike. Branchiae are 

 present from the fifth setigerous segment; they are thick, club-shaped
