xxi COLOSSENDEIDAE EURYCIDIDAE 533 



in the Southern Ocean, has a span of about two feet. The North 

 Atlantic C. proboscidea and Antarctic C. australis are very closely 

 related to one another. Carpenter would retain the genus 

 Rhopalorliynchus for R. kroyeri, \V.-M. (Aridamans), 7Y. clai-i/>f*. 

 Carp. (Torres Straits), and 7.'. tenuissimus, 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 weberi, 

 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 Harmon M) ; 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. 



Eurycide, Schiodte (1857) (Zetes, Kriiyer, 1845): Appendage 

 I. with two-jointed scape, without chelae in adult ; one species (E. 

 hispida, (Kr.)), from the North Atlantic and 

 Arctic, and two others from the East Indies, 

 recently described by Loman. lim-inm 

 arenicola, Dohrn (1881), is nearly allied. 

 Ascorhynehus, G. O. Sars (1876) (Gnampto- 

 rhynchu*, Bohm, 1879; Scaeorhynhus, 

 Wilson, 1881), very similar to Eurycide, 

 with which, according to Schimkewitsch, it should be merged, 

 includes large, smooth, elongated forms, with long neck and 

 expanded frontal region, and a long proboscis lacking the long 

 scape that supports the proboscis in Ewydde; about twelve 

 species, world-wide, mostly deep-water, garana castelli, Dohrn, 

 from Naples is akin to the foregoing genera, but seems to deserve 

 generic separation from B. arenicola. Ammothea ln<ji<-<>lli*, 

 Haswell, from Australia, is, as Schimkewitsch has already 

 remarked, almost certainly a Euri/rld,-. 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 chelopborea 

 are much reduced, the palps are absent; the ovigerous legs are
