NO. 1 hartman: goniadidae, glyceridae, nephtyidae 41 



Goniada longicirrata Monro (1937, pp. 285-286, figs. 12 a-c) from 

 south Arabia and the Red Sea, is not the same Arwidsson's species, 

 since it has proboscidial chevrons; this name is referred to Goniada 

 emerita, above. 



Distribution. — Ophioglycera longicirrata is thus known only from 

 Terand-Vaso, west Africa. 



Genus Goniadopsis Fauvel, 1928 

 Type G. agnesiae Fauvel 



This genus is characterized for having the body divided into 3 

 regions, an anterior one with uniramous parapodia provided with short 

 cirri and falcigerous composite setae, an intermediate region with uni- 

 ramous parapodia with long cirri and spinigerous composite setae, and a 

 posterior region with biramous parapodia in which notopodia have 

 acicular setae and neuropodia have long, spinigerous, composite setae. 

 The proboscis lacks chevrons. 



Only 2 species have been referred to the genus, they are G. agnesiae 

 Fauvel (1932a, p. 122) from the Indian Ocean, and G. incertae Fauvel 

 (1932a, p. 122) from Burma. A third, described as Glycinde maskal- 

 lensis Gravier (1904, p. 475) from the Red Sea, is here believed con- 

 generic; it is newly named Goniadopsis maskallensis (Gravier). The 

 genus is not known to be represented outside the stated areas. 



Genus Goniadella, new genus 

 Type G. gracilis (Verrill) 



The body is slender; it consists of anterior and posterior regions 

 but they are not sharply set off from each other; a middle region is 

 lacking. The prostomium is clearly annulated and has about 8 

 rings. It ends distally in 4 long, slender, Particulate antennae. There 

 are eyes in the basal, or perhaps also in the distal ring. The proboscis 

 is covered with organs of a single kind and there are paired chevrons 

 at the sides, near the base. Macrognaths are dentate, probably ventro- 

 lateral in position. Micrognaths consist of small H-shaped pieces in 

 dorsal and ventral arcs. 



Parapodia are uniramous through about 30-35 segments and there- 

 after biramous. Neuropodia have a simple, longer, presetal lobe and a 

 simple, blunt, postsetal one. Ventral and dorsal cirri are elongate and 

 triangular. Notosetae are simple. Neurosetae are composite; they in- 

 clude both falcigerous (pi. 5, fig. 5) and spinigerous ones in all para- 

 podia.
