IDENTITY OF SOME MARINE ANNELIDS—HARTMAN 103 
trophores occur on segments 2, 4,5, 7,9 * * * 23, 26, 29, 32, 
34, 37, 40, 43, a total of 19 pairs. All elytra except the last have been 
lost; they are tiny, nearly circular, translucent white, with entire 
margin. 
The first segment is provided with long dorsal and ventral cirri; 
the former extend forward about as far as the long palpi; the ven- 
trals are somewhat shorter. In addition to a stout, pointed aciculum, 
two (or 3 or 4) stout, blunt, yellow setae project from the para- 
podium. The second segment has a slender, tapering, notoacicular 
lobe but no setae; this is typical of more posterior parapodia. The 
neuropodium has a long, triangular, presetal lobe, from which the 
aciculum extends, and a very much shorter, postsetal lobe. Neuro- 
podia on segments 4 to 14 have a unique modification consisting of 
an expanded, glandular area ventral to the triangular acicular lobe; 
it extends to the ventral face of the parapodium. This structure is 
large, conspicuous on segments 4 to 8 and gradually diminishes in 
size to the fourteenth segment. Dorsal cirri are long throughout, 
extending far beyond the parapodial lobes, but are shorter than the 
longest setae. Ventral cirri are slender, tapering, and inserted near 
the place where the ventralmost setae emerge. 
Neurosetae are of two intergrading kinds, including (1) more nu- 
merous long, slender setae with many relatively coarse, widely spaced 
teeth on the outer side, tapering distally and ending in a fine, bifid 
tip, and (2) 7 or 8 shorter, coarser, inferior setae with a shorter 
serrated region, and ending in a coarser bifid tip. In these respects 
it agrees with Z. maculata Potts (1910, p. 344) originally described 
from Zanzibar. 
The monotypic genus, Harmopsides Chamberlin, was originally 
separated from Lepidasthenia because it was thought to have fewer 
elytra; since, however, the collection consists of only immature in- 
dividuals, this character has no real significance. Monro (19387, p. 
262) suggested that this might represent a juvenile stage of Z. macu- 
lata Potts. In the latter, however, no mention has been made of 
glandular areas on segments 4 to 14, such as are present in Z. natans. 
In other respects they agree rather well.

Lepidasthenia alba HarTMANn, 1938a, p. 114. 
I have again examined the types of P. alba and P. lucida and 
must conclude that they represent the same species. Earlier (1938a, 
p. 114) I referred them both to Lepidasthenia but separated them 
on the proportionate lengths of parapodia and the relative lengths
