with conspicuous, slightly asymmetrical lateral 
swellings. First antenna consisting of 24 free 
segments, segments 8 and 9 fused, reaching end 
of cephalothorax. Segments 7, 8, 13, 17, 20, 
23, 24 each armed with 1 large, smooth seta; 
first segment bearing 2 long, plumose setae. 
Endopod of second antenna smaller than 
exopod, exopod consisting of 7 segments. First 
maxilla with 10 spines on first inner lobe, 0 
setae on second inner lobe, 1 seta on third inner 
lobe, 1 seta on second basal segment, 6 setae on 
endopod, 11 setae on exopod, and 9 setae on 
outer lobe. One seta each on third to fifth lobe 
of second maxilla developed as spine. Second 
basipodal segment of maxilliped nearly twice 
the length of first segment. Exopods of first to 
fourth swimming feet 3 -segmented. Exopodal 
segments of first foot indistinctly separated from 
each other. Each of the segments bearing 1 
external spine. Endopod of first swimming 
foot consisting of 1 segment. Endopod of 
second swimming foot 2 -segmented, of third 
foot 3-segmented; fourth foot broken short. 
Posterior side of second basipodal segment of 
fourth foot smooth. Terminal spine of exopods 
(intact only on left second and right third 
swimming foot) strong, denticulate. Fifth feet 
absent. Total length 9.00 mm. Flolotype: 
USNM 120526. 
The male is unknown. 
Remarks: The genus Batheuchaeta was estab- 
lished by Brodsky (1950) to accommodate one 
species, B. lamellata, which he found in the 
northwestern Pacific. The female of the new 
species proposed here, B. enormis, differs from 
the description of the genus given by Brodsky 
in the following points: The genital segment is 
slightly asymmetrical, it is symmetrical in 
Batheuchaeta; the posterior margins of the ab- 
dominal segments are smooth, they carry teeth 
in Batheuchaeta; the second maxilla carries 3 
spines, 1 each on lobes 3 to 5, Batheuchaeta 
has one spine each on lobes 4 and 5 only. 
Euchirella speciosa n. sp. 
Figs. 14—19 
occurrence: Station 29, 1 female. 
diagnosis: Female. Head and first thoracic 
segment fused. Fourth and fifth thoracic seg- 
ments fused. Anterior portion of head smoothly 
rounded in lateral view, without crest. Genital 
segment asymmetrical, in dorsal view right side 
smooth, left side with two small swellings. 
One-pointed rostrum of moderate size, directed 
downward. First antenna 24-segmented, seg- 
ments 8 and 9 fused, reaching furca. Endopod 
of second antenna about 1/4 of exopod. Outer 
lobe of terminal segment of endopod with 5, 
inner lobe with 4 setae. Endopod of first swim- 
ming foot 1 -segmented, exopod 2-segmented 
with 3 straight external spines. Endopod of 
second swimming foot 1 -segmented, exopod 
3-segmented. Endopods and exopods of third 
and fourth swimming feet 3-segmented. Pos- 
terior surface of first basipodal segment of 
fourth swimming foot with 2 rather strong, 
unequal spines. Total length 4.92 mm. Holo- 
type: usnm 120527.
