XXI COLOSSEN DEIDAE—-EURYCIDIDAE 533 
in the Southern Ocean, has a span of about two feet. The North 
Atlantic C. proboscidea and Antarctic C. wustralis are very closely 
related to one another. Carpenter would retain the genus 
Rhopalorhynchus for R. kréyeri, W.-M. (Andamans), 2. clavipes, 
Carp. (Torres Straits), and RL. tenuwissemus, Haswell (Australia), 
all more or less shallow-water species, excessively attenuated, 
with the second and third body-segments elongated, the caudal 
segment excessively reduced, the club-shaped proboscis on a 
slender stalk, and other common characters. Pipetta weber, 
Loman (1904), is a large and remarkable form from the Banda 
Sea, apparently referable, in spite of certain abnormal features, 
to this family; the proboscis is extraordinarily long and slender ; 
the palps have eight joints, the ovigerous legs eleven. 
Fam. 3. Eurycididae (Ascorhynchidae, Meinert)— Appen- 
dage I. more or less reduced; appendage II. 10-jointed (absent 
in Hannonia); appendage III. 10-jointed, clawed, with more 
than one row of serrated teeth; proboscis movably articulated 
and more or less bent under the body ; auxiliary claws absent. 
Hurycide, Schiédte (1857) (Zetes, Kroyer, 1845): Appendage 
I. with two-jointed scape, without chelae in adult ; one species (£4. 
hispida, (Kr.)), from the North Atlantic and 
Arctic, and two others from the East Indies, 
recently described by Loman. Parana 
arenicola, Dohrn (1881), is nearly allied. 
Ascorhynchus, G. O. Sars (1876) (Gnampto- 
rhynchus, Bohm, 1879; Scaeorhynchus, 
Wilson, 1881), very similar to Hurycide, 
with which, according to Schimkewitsch, 1t should be merged, 
includes large, smooth, elongated forms, with long neck and 
Fic. 283.— Hurycide his- 
pida, Kr. ; side view. 
expanded frontal region, and a long proboscis lacking the long 
scape that supports the proboscis in Hurycide; about twelve 
species, world-wide, mostly deep-water. Barana castelli, Dohrn, 
from Naples is akin to the foregoing genera, but seems to deserve 
generic separation from B. arenicola. Ammothea longicollis, 
Haswell, from Australia, is, as Schimkewitsch has already 
remarked, almost certainly a Hurycide, as is also, probably, 
Parazetes auchenicus, Slater, from Japan. 
Hannonia typica, Hoek (1880), from Cape Town, is a 
remarkable form, lately redescribed by Loman. The chelophores 
are much reduced, the palps are absent; the ovigerous legs are
