CRUSTACEA COPEPODA. II. 57 
Lernzeopodopsis n. gen. 
Body of the female divided by a very recurved dorsal line, somewhat behind the insertion of the 
maxillee, into cephalothorax and trunk (fig. 3 a). In advance of the front margin of the base of the maxillee 
the cephalothorax is produced much forward as a very oblong triangle with the front end narrow and obtuse 
(figs. 3 a—3 b); the maxillipeds originate near the middle between the front end and the origin of the maxille, 
while the other appendages are extremely small and arranged close together at the narrow front end. — 
The trunk terminates in a pair of small tubercles. 
Antennulz (a), seen from below (fig. 3 d), originate below and slightly behind the antennz; they 
are a little shorter than the antennee, 2-jointed. — The antenne (figs. 3c and 3d, a’) are essentially pro- 
jected along the sides of the proboscis; they are biramous, but both rami are simple, short, broad and rounded, 
without spines. — The proboscis is very thick and directed horizontally forwards, so that the mouth with 
its rather broad, fringed lamella is terminal on the head. — The maxillule (fig. 3d, mx’) as usual on the 
sides of the oral cone; each maxillula is an oblong plate with two minute, setiferous knots on the terminal 
margin. — The maxille are very long (fig. 3 a), fused along the major distal part and terminating in a single 
bulla. — Maxillipeds (fig. 3 e) consist of a large, oblong, thin-skinned part, on the end of which the extremely 
small well chitinized elements are found, viz. an oblong joint and the claw-shaped portion. 
Remarks. — Of the new species, on which this genus is founded, only the female is known. It has 
at first sight a considerable likeness to forms of the genera Levneopfoda and Lerneopodina, but a closer in- 
vestigation shows that it occupies an isolated position within the family. The strongly produced, triangular 
head with the extremely small appendages is very curious; the antennule and especially the maxillipeds 
are very interesting.

(Pl. IV, figs. 3 a—3 e). 
Female. — The cephalothorax may be said to possess a moderately developed carapace, which 
posteriorly terminates in a very convex margin situated somewhat behind the origin of the maxillee; it is 
a little more than twice as long as broad and in the median line about as long as the trunk. The head in 
advance of the anterior margin of the base of the maxillee is somewhat more than half as long again as broad, 
oblong-triangular. — The trunk is somewhat depressed, about twice as long as broad, with the lateral margins 
feebly convex; the end is broadly rounded without any real processes, but at the middle a little incised 
between a pair of quite small protuberances. — No ovisacs. 
The antennule (fig. 3d, a) are 2-jointed; the first joint is very oblong, considerably longer than 
and twice or three times as thick as the second, which is very slender and terminates in a moderately long 
seta. — Antenne, proboscis, and maxillule are mentioned sufficiently in the description of the genus; figs. 3 c 
and 3 d may convey a full idea as to various particulars, — The maxillz are nearly more than twice as long 
as the entire body; they originate on the sides of the cephalothorax, proceed forwards and from somewhat 
in front of the mouth they are completely fused; towards the end the appendage formed by that fusion is 
gradually acuminated to the moderately short and thin thread which terminates in a minute bulla of normal
