Archive image from page 149 of The Danish Ingolf-Expedition (1915). The Danish Ingolf-Expedition danishingolfexpe19150304ingo Year: 1915 142 COPEPODA oped setigerous process inwards, and the second segment has a similar one at the base in addition to ones sitting in the middle as well as terminally (text-fig. 38 f). The mandibulae and maxilhilae do not show any features which were not mentioned in Giesbrecht's description. The maxillae are very much like fig. 5 c of Ch. abyssalis. The third basipodite of the maxillipeds, which is almost twice as long as the Basp. \<si2 and distinctly three times as long as the Ri, has along the exterior margin almost from base to tip on the posterior surface a low transparent lamella with a distinct concavity in the middle; the fourth lobe of the second basipodite is placed posteriorly, and has a fairly long sensory lobe surrounded by slen- der hairs, in addition to three setae (text-fig. 38 g); anteriorly, and somewhat removed from the tip, a rounded protuberance is found in the second basi- podite, probably corre- sponding to that of E. cur- ticaiida. The first pair of legs has the inner margin of the last basipodite .slightly convex, as seen in text-fig. 38 h; the Se of Ri I has no accessory tooth in the second pair of legs, and no trace of it in the third and fourth pairs (text-fig. 381); the inner margin of the second basipodite in the fourth pair of legs is in most specimens completely smooth, but in some has one or two short stiff hairs corresponding to Giesbrecht's 'sparlichen kurzen Spitzen'. The glandular pores are like those of Undeuchate. The elevation in front of the labriim is smooth and fairly well raised; along the posterior margin the labrum proper has as usual a median row of long and slender hairs divided into a right and a left part, and a lateral shorter one, of more spine-shaped setae. The oral surface of the labrum (fig. 4 b) is like that of Undeuchcete. The first group of the longitudinal series is place
