green mud; 4436, off San Miguel Island, 264-271 fathoms, green mud 

 (type and 71 others); 4547, off Point Pinos Lighthouse, 1083 fath- 

 oms, soft gray mud. 



Amage anops (Johnson) 



This species, at first thought to be distinct under the name 

 A. perfecta, is now regarded as identical with Johnson's species or 

 at most as only a su])species. The specimens all have twelve instead 

 of fourteen or fifteen abdominal segments and most of the thoracic 

 uncinihave five teeth, though some are provided with an additional 

 small upper sixth tooth as in Johnson's figure. 



Stations 4322, off Point LaJolla, 110-199 fathoms, soft green 

 mud; 4454, same locality, 65-71 fathoms, green mud and shells; 

 4525, same locality 222 fathoms, soft gray mud. 



Amage scutata sp. nov. Plate XVII, figs. 19-24. 



Form elongated fusiform or subcylindroid, with tapered abdomen 

 Nearly terete, much more slender than A. anops. Type (with eggs) 

 25 mm. long, maximum width 4 mm., length of abdomen 7.3 mm. 

 Thoracic segments 17, abdominal 10. 



Anterior border of prostomium a thin, erect, entire, vertical and 

 transverse, semicircular plate from the middle of the anterior 

 border of which projects a small papilla or palpode from which 

 a low ridge runs to the dorsal border of the mouth. At the root of 

 its posterior face is a transverse thickening and behind this the 

 pair of nearly united transverse nuchal slits, themselves bounded 

 by a broad transverse annulus, the lateral ends of which are cut 

 off by a pair of shallow furrows and probably represent the lateral 

 prostomial lobes, which, however, are excluded from the anterior 

 border of the prostomium. Tentacular membrane short, not 

 projecting beyond border of prostomium, horseshoe-shaped, with 

 one deep median plication. Tentacles grouped in a pair of small 

 lateral tufts of about twelve each of very short ones and a pair of 

 more medial and dorsal tufts of about four each of longer ones 

 about one-half width of body. All are smooth and clavate. No 

 eyes. 



Peristomium reduced and obscure dorsally, produced forward 

 ventrally into a stiff glandular lip having a much furrowed and 

 crenulated margin and small but somewhat prominent inturned 

 lateral lobes. Somite III, along with the two succeeding somites 

 is abruptly enlarged and tumid above to form the branchial pedistal. 

 Its ventral plate is produced into a pair of small lateral lobes or 

 wings resembling those of the lower lip. Somites IV and V are 

 short and crowded; VI is somewhat longer. These three bear 

 parapodial tubercles and gills and prominent ridge-like ventral 

 gland-plates.
