The outer-edge spines on the exopodite of the second pair of feet are comparatively 
short and stout. The outer-edge spine on the second joint is longer and stouter than the others, 
but it falls considerably short of the base of the first outer-edge spiné on the third joint. 
The third and fourth pairs of feet are almost similar to those of Fuchaeta marina. 
Male — length 2,7 mm. 
The males are very like those of Luchaeta marina in general appearance, but are 
easily recognised by the difference of the armature on the projection of the second joint of the 
exopodite of the left fifth foot. The spinules are small and closely set, and the apex of the 
projection is deeply notched. The second joint of the left exopodite is furnished with four long 
and moderately strong spines on the inner margin, opposite the apex of the projection. 
The female of Zuchaeta wolfendent, is undoubtedly the same as the form which is wrongly 
described and figured by WoLrEeNDEN as Luchaela marina, in his report on the Copepoda collected 
by J. STANLEY GARDINER around the Maldive Islands. There appears to be some confusion 
between WoLFENDEN’s description and figure of the exopodite of the second pair of feet, which 
renders the identification rather difficult at first sight. The description of the outer-edge spines 
on the exopodite of the second pair of feet agrees with what is found in typical Etuchaeta 
marina, but does not agree with the figure 8 on plate C. The description of the spines both 
of Euchaecta indica and of Euchaeta marina in WoL¥ENDEN’s report, has evidently been drawn 
Dp yiiom)) the eure 16 on plate C. 
This species appeared to be fairly well distributed in the Malay Archipelago. Males and 
females were not uncommon in the plankton collected by the ‘Siboga’. The species was present 
at the following stations.

Euchaeta wolfendent may prove to be widely distributed in the warm seas. Owing to 
its general resemblance to Euchaeta marina, however, it may be easily overlooked. I have 
specimens of this species from the plankton samples collected by Professor Hrerpman between 
Aden and Colombo, during his traverse to Ceylon and back in 1903. 
The species is named in compliment to Dr. R. N. WotrenpeN, whose investigations of the 
plankton of the deep water of the North Atlantic, have revealed a number of interesting Copepoda. 
Genus Paraeuchaeta nov. 
This genus is established for the reception of the Awchacta-like forms of which Borck’s 
Etuchaeta norvegica is the type. 
The females are distinguished from true Azchaeta by the armature of the spines on the 
apex of the Tist maxillipedes. These spines are densely furnished with fine short spinules only. 
The long spinules, which are so characteristic in true Awchaeta, are entirely absent.
