NO. 1 hartman: goniadidae, glyceridae, nephtyidae 47 



on area I (pi. 6, fig. 5) have the spine directed orally; those on area 

 II (figs. 7 to 12) are directed obliquely back and mid-dorsally ; those on 

 area III have the spine directed ventrally (they have their long axis 

 at right angles to that of the body). Those on area V have the spine 

 directed obliquely orally and midventrally. The organs on area I are 

 smallest but those on area V may be vestigial or absent. Those on area 

 II are not only the largest, but have articulating bases. 



The proboscidial organs of Glycinde that most nearly resemble the 

 corresponding structures in Goniada are the smaller ones on area I 

 (likened to the dispersed ones) and area IV (to the chevrons). In 

 Glycinde most of the specialized structures appear to function for grasp- 

 ing and holding; those on area IV, however, may function to main 

 stabilization of the long body with the greatly extensile proboscis. The 

 enormous length of the latter in species of this genus is notable, and 

 can be appreciated by observing that the eversible part includes not only 

 that shown everted (fig. 1) but also the portion extending nearly to the 

 left hand side of the drawing (where the paragnaths are located). 



In so far as has been observed, the occurence and the arrangement 

 of these parts for different species of Glycinde are singularly alike, but 

 the structural details of the separate pieces differ from one species to 

 the next. Closer scrutiny of other species than those detailed herein, 

 may reveal greater differences within the genus. 



The known species of Glycinde are widely distributed and over half 

 of them have been described from the Western Hemisphere. They are 

 as follows: 

 G. armata (Kinberg), 1866, p. 247, from southern South America (see 



Monro, 1936, p. 143, for redescription). 

 G. armigera Moore, see p. 49. 



G. bonhourei Gravier, 1906, pp. 142-145, from the Red Sea. 

 G. dorsalis Ehlers, 1905, pp. 38-40, from New Zealand. 



This is further recorded by Augener (1924, p. 439) in which 

 biramous parapodia occur from segment 38-40, and Augener 

 (1927b, p. 351) in which they occur from segment 30, with the 

 third body region from segment 54-55. So great a variation is 

 hardly to be expected within a single geographic area (Aus- 

 tralia). 

 G. kameruniana Augener, 1918, pp. 398-399, from West Africa. 



According to its author, this species is incompletely known. 

 G. multidens Miiller, see p. 56. 



G. nordmanni (Malmgren), 1866, p. 409, from western Europe (see 

 Fauvel, 1923, p. 394, fig. 155, for description).
