Family chaetopteridae 
KEY TO THE SPECIES FROM MARSHALL ISLANDS 
1. One pair of tentacles 2 
1. Two pairs of tentacles 
Phyllochaetopterus 3 
2. Two or three median segments; the notopo- 
dia of these segments separate and conical 
in shape Mesochaetopterus minutus 
2. Five median segments with the notopodia 
of the first two aliform in shape and the 
last three cup-shaped . . Chaetopterus sp. 
3. Larger, 15 anterior segments; 3 smaller 
modified setae on the fourth segment; about 
16 segments to mid-region 
Phyllochaetopterus ramosus 
3. Smaller; 10—18 or more anterior segments; 
1 smaller modified seta on fourth segment; 
5-28 segments to mid-region 
Phyllochaetopterus socialis 
Chaetopterus sp. 
Hartman, 1954^, p. 637. 
One incomplete specimen, which was similar 
to the one reported by Hartman, was taken from 
sand in 10 ft of water on the lagoon side of 
Parry Island, Eniwetok Atoll. This sandy area 
had a heavy concentration of two other mem- 
bers of the Family Chaetopteridae, Mesochae-. 
topterus minutus and Phyllochaetopterus ramo- 
sus. Repeated attempts were made to secure 
additional material of Chaetopterus sp. without 
success. Hartman’s report was based on a single 
individual taken from the lagoon side of Ronge- 
lap Island, Rongelap Atoll. 
Mesochaetopterus minutus Potts 
Fauvel, 1953, pp. 342-4, fig. 178,2/ Hartman, 
195 4a, p. 629. eniwetok: Parry (0,L), Igurini 
(L), Rigili (L), Bogombogo (0,L), Japtan 
(O), and Bogen (O). majuro: Uliga (L). 
Cosmopolitan in warmer seas. 
Phyllochaetopterus ramosus Willey 
Willey, 1904, p. 293, pi. 5, figs. 133-136. 
eniwetok: Parry (0,L), Rigili (L), Bogom- 
bogo (O), Aaraanbiru (L), Japtan (L). Hart- 
man reported two specimens from Bikini Atoll 
which she believed were to be compared with 
P. ramosus. They differed from this species and 
the present account by the fewer number of 
segments to the anterior region and by a greater 
number of modified setae on the fourth seg- 
ment. Ceylon and Marshall Islands.
