“One specimen only was found, in the bottle marked 19 a.c. 
Another specimen occurred in the sample marked 20,” 
Evucananus crassus Gbt. 1888, Atti Acc. Line., and 1892, Fauna 
u. Flora Neapel, v. p. 19. 
“This species was of not infrequent occurrence, especially in 
the bottles marked B 1 and 13 & (2 to 0) and 137 (100 to 0). 
“The writer also has frequently noted its occurrence in the 
Faeroe Channel.” 
GAETANUS MAJOR Wolfenden, sp. n. 
“Two examples of this genus (Gaetanus) were found in 
Dr. Fowler's collection marked 19 @ (480 to 350 fathoms). The 
copepod very greatly resembled Gaetanus armiger Ght., but the 
anterior antenne were longer, reaching beyond the furca by the 
length of the last joint; the spines of the last thoracic segment 
were comparatively shorter, the lst abdominal segment and the 
anal segment shorter, and the fureal segments only as long as 
broad (longer than broad in G@. armiger), and each abdominal 
segment had a row of pectinations on the posterior border. The 
saws of the swimming-feet possessed more teeth; the abdomen 
was not nearly half the length of the cephalothorax, and the 
whole length of the animal was 5:3 mm. In all these points it 
differed from the typical G. armiger, the size of which reaches 
only about 3 mm., and justifies its being made into a separate 
species,” 
Garpius Gbt. 1895, Bull. Mus. Harvard. 
“A good many examples of this genus occurred in the deep- 
water collections of Dr. Fowler, e.g. in the bottle marked Meso- 
plankton 20 (500 to 100 fathoms). 
There is no doubt that in the Faeroe Channel there are two 
kinds of Gaidius—one agreeing in every particular with the 
Gaidius pungens of Giesbrecht; the other, a larger species, also 
differing in the segmentation of the Ist and 2nd feet. Gaidius 
pungens Gbt. has the exopodite of the Ist foot with only two 
segments and the endopodite of the 2nd foot with only one seg- 
ment; whereas the northern species has a 3-jointed exopodite 
of the 1st foot and a two-jointed endopodite of the 2nd foot. 
There are other minor differences. In size the northern species is 
much larger; Gaidius pungens Gbt. being 45 mm., as compared 
with about 3mm. The Chiridius tenwspinis of G. O. Sars is the 
Same species, all being characterized by the peculiar series of 
lamellar appendages of the basipodite of the 4th foot.” 
PSEUDAETIDEUS ARMATUS Wolfenden. 
“Some examples of this species occurred in Dr. Fowler’s col- 
lection. It was drawn and described (in MSS. only) before the
