22 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.15 



at its distal end it is very much prolonged at its front, or cutting, edge 

 and distinctly serrated (fig. 6) ; the lowest edge, at the back, is entire 

 unless worn when it may appear frayed or split. The sides are grad- 

 ually sloping. The appendage is long, pointed and knifelike along its 

 length. It has a single row of small teeth (figs. 5, 7). Usually the artic- 

 ulations are seen in three-fourths view (fig. 7) giving the impression 

 that the deepest part of the shaft is at the side instead of the back. A 

 correct view can be had by slightly rolling the setae when observed 

 under high magnification, or by detaching shaft from appendage. 



Individuals identified as G. annulata Treadwell (1914, p. 198) 

 from southern California have been examined and found to be other- 

 wise, as follows: Station LXXI, off La Jolla in 15-57 fms, station 

 LXXIII, off San Diego in 57-97 fms and station 1112, off La Jolla 

 in 45 fms go to G. brunnea (see above). The record from station 

 LXXIII off San Diego in 57-97 fms goes to Glycinde armigera (see 

 below). A specimen reported from station 1122 off La Jolla in 100 fms, 

 has not been found. All others are deposited in the Allan Hancock 

 Foundation. 



G. annulata Fauvel (1932a, p. 121) reported and redescribed from 

 an individual off south Ceylon in 660 fms, is here believed to be dif- 

 ferent, in spite of similarities. The notopodium has a longer, conical, 

 presetal lobe and a shorter, broader, postsetal one. Dorsal cirri are 

 foliaceous and the proboscis has about 20 V-shaped pieces in each chev- 

 ron. In these respects the 2 are similar. They differ thus: in G. annulata 

 Moore the parapodial change is more or less abrupt at segment 33 or 34 ; 

 in Fauvel's species 27 segments are uniramous, 21 are transitional, so 

 that 48 segments are concerned. In the first dorsal cirri are sessile, in 

 the second they are pedunculate. In the first notosetae are nearly twice 

 as thick as neurosetae, in the second they are very slender and hairlike. 

 The proboscidial organs are of a single kind in the first, or not notice- 

 ably different on ventral and dorsal sides of the proboscis. In the second 

 they are arranged in longitudinal rows, larger on the dorsal than on 

 the ventral side, and the latter are often depressed and distally bidentate. 

 In the first the prostomium is distinctly annulate, whereas in the other 

 it is indistinctly annulate. 



G. echinulata Grube (1870, p. 67) from Brazil has been question- 

 ably referred to G. annulata Moore (Fauvel, 1932a, p. 121) but this 

 seems very doubtful, even though the Brazilian species is incompletely 

 known. In Grube's species the parapodial change is said to be at seg- 

 ment 46 instead of 33-34 and the chevrons number only 14, instead of 

 20, pieces on a side.
