COPEPODA—BRADY. 17 
2. PARACALANUS MARIA! sp. nov. 
(Plate I, figs. 9-14.) 
Male.—This species, of which two males and two females only have been 
observed, differs from the foregoing in several rather important points. The pro- 
portionate lengths of the abdominal segments, which in P. Marie are as follows :— 
in eh eh Ze 
division. The basal joint of the posterior maxilliped is produced in a mamuilliform 
fashion and is covered with three rather large sete, more conspicuously than in 
P. parvus. The third and fourth pairs of swimming feet have the distal portion 
of the last joint of the exopodite armed with a series of very minute spines; the other 
The fourth segment, however, shows an apparently incomplete line of 
swimming feet are entirely devoid of spines. The feet of the fifth pair are similar to 
those of the male P. parvus, except that the joints of the longer branch are nearly equal 
in length instead of being very unequal, as in P. parvus.* The specimens on which this 
description is based were taken at Station 2—off Maria Island, Tasmania. 
Family PSEUDOCALANID &. 
Genus CLAUSOCALANUS Giesbrecht, 1888. 
CLAUSOCALANUS FURCATUS (Brady). 
Drepanopus furcatus Brady, 1883, p. 77, plate IV, figs. 1, 2; plate XXIV, 
figs. 12-15. 
This species, which seems to me indistinguishable from C. arcuicornis Giesbr., 
was found in two nettings from Stations 2, 5,8 and 18. I find it impracticable on the 
strength merely of the segmental lengths of the abdomen and furca, which are chiefly 
relied upon by Dr. Giesbrecht and Andrew Scott, to diagnose the two species with any 
reasonable accuracy. 
Genus SPINOCALANUS Giesbrecht, 1888. 
SPINOCALANUS GIESBRECHTI sp. nov. 
(Plate VIII, figs. 21-25.) 
Male.—Anterior antenne comparatively short, reaching to the level of the 
second pair of natatory feet; endopodites of the third and fourth pairs of feet in the 
male armed with spines as in the type species, the exopodites bearing on the distal 
segment three sets of very minute spines, about three or four spines in each group; 
fifth pair of feet imperfectly seen, the foot of each side made up apparently of three 
linear joints with three terminal sete; abdomen composed of four nearly equal segments. 
Female-—Abdomen of three segments, third more than equal in length to the 
combined anterior segments; fifth pair of feet rudimentary, composed of two or three 
stout joints with a minute inner branch. 
eThe fifth pair of the female similar to those of P. parvus.
