CRUSTACEA COPEPODA. II. 63 
end and the base of the maxillipeds is not much shorter than the dorsal line from the base of the proboscis 
to the posterior end. — The antennule (fig. 6 f) are 3-jointed, with a spine on the posterior side of second 
joint, while third joint has 3 long, terminal spines, the median one very thick. — Antennz (fig. 6 f) with 
the rather long sympod 2-jointed; endopod not marked off, unjointed, without any spine; exopod 2-jointed 
with a minute terminal spine. — Maxillule (fig. 6 f) normal; the palp somewhat short and slender, with 
a well developed terminal spine. — Maxille and maxillipeds of moderate size, proportionately smaller than 
in Clavella uncinata or C. Stichei. 
Length 0.55 mm. (proboscis not included). 
Occurrence. —- Taken on rays of the anal fin of specimens of Macrurus secured by the “Ingolf” 
at two stations. 
Davis Strait: Stat. 35: Lat. 65°16’ N., Long. 55°05’ W., 362 fathoms, temp. 3°.6; 2 fine females (one 
with a male) on the distal part of the anal fin of a large Macrurus Fabricii. 
— — Stat. 27: Lat. 64°54’ N., Long. 55°10’ W., 393 fathoms, temp. 3°.8; 1 female at the 
end of a ray in the anal fin of M. Fabricit or M. rupestris. 
78. Clavella gracilis n. sp. 
(PL IV, figs. 7 a—7 f). 
Female. — Very small and extremely slender. Cephalothorax even more than twice as long as 
_ the trunk and recurved along its dorsal side; it decreases somewhat in thickness from base to end; the head 
is not marked off and not enlarged; the middle part of the front margin somewhat convex. — The trunk 
is slender, distinctly depressed, with the posterior margin nearly straight and no vestige of any protuberance. 
— Ovisacs distinctly or considerably longer than the trunk, with two longitudinal rows of eggs or sometimes 
(fig. 7 a) in their proximal part with a single row. 
Antennule (fig. 7 b) 3-jointed, with first joint thick, second somewhat shorter than the first, the 
third slightly longer than the two others together and terminating in a hook. — Antenne (fig. 7 c) turned 
somewhat inwards, biramose; exopod about as long as the sympod, 2-jointed, first joint considerably thicker 
and much longer than the second, which terminates in two small spines; endopod undivided, obliquely ex- 
panded, broader than long, and without equipment. —- The proboscis moderately long, reaching slightly 
beyond the antennze when these are bent inwards; the terminal striated membrane is rather broad. — Maxil- 
lulz (fig. 7d) with the two terminal processes rather short, unequal in length and each terminating in a 
seta; the palp minute, spiniform. — Maxille (fig. 7 a) extremely short; a bulla in the usual sense does not 
exist, but a dark-brown thread, which is round at the base and then somewhat enlarged or thickened to 
far beyond the middle or to near the end, is more than half as long as the trunk. — Mazxillipeds (fig. 7 e) 
somewhat long; first joint considerably more than twice as long as broad, with the distal oblique margin 
sinuate; second joint armed below somewhat from the end with a spine; a curved spine or accessory claw 
is very distinct. 
Length of cephalothorax 2.6mm., of the trunk 1.2mm., of an ovisac 1.24 mm.
