The mastax is fairly large and of the normal type; the fulcrum 
is sKghtly expanded posteriorly, the manubria slender, rodlike 
and not crutched. The gastric glands are small. 
The ganglion is elongate and saccate; the eyespot is frontal and 
double, the two spheres rather wide apart. No retrocerebral organ 
is present. The dorsal antenna is unusually far back on the head. 
Total length 160-165/a; toes 28-30/a. 
Cephalodella marina is common among algae and vegetable 
detritus in shallow tidepools near Atlantic City, New Jersey. It 
is related to C. mineri, but is readily distinguished by the very 
slender toes and the uncrutched manubria, the more oblique corona 
and larger head.

Plate XXVI, figures 3-5. 
The body is elongate, slightly compressed laterally and strongly 
gibbous dorsally. The head is small, distinctly deflexed and 
strongly oblique anteriorly. The neck is well marked. The ab¬ 
domen increases rapidly in width for about two thirds of its length; 
at this point the dorso-ventral depth is almost twice the depth of 
the anterior margin; the posterior third of the dorsal edge curves 
slightly downward. The lorica is flexible, but the plates are fairly 
distinct; the lateral clefts are narrow anteriorly and increase 
slightly in width towards the posterior end. The foot is long, 
conical and extremely broad at the base; the tail is small and some¬ 
what beyond mid-length. The toes are relatively short and robust, 
very slightly enlarged at the base and taper gradually to slender, 
acute points; their length is about one fifth of the total length. 
The foot glands are very large and pyriform. 
The corona is strongly oblique and convex without projecting lips. 
The mastax is fairly large and of the typical form; the fulcrum 
is relatively short, stout and parallel-sided without any expansion 
at the posterior end; the manubria are long and crutched. The 
gastric glands are small. 
The ganglion is moderately long and saccate; the eyespot is 
frontal and double, the two halves fairly wide apart. No retro- 
cerebral organ is present. The dorsal antenna is far back on the 
head, a short distance in front of the neck. 
Total length 200-210/a ; toes 40-44/a ; trophi 40/a.
