HAUSTORIIDAE 



9i 



Type of <J. 



Cardenio paurodactylus, Stebb. (Fig. 43). 



Stebbing, 1888, p. 806, pi. liii; 1906, p. 126. 

 Schellenberg, 1926 b, p. 195. 



Occurrence: 1. St. MS 65. South Georgia. 1 S 4'5 mm. 

 2. St. 164. South Orkneys. 1 $ 10 mm. 



Description $ . Pleon obscurely denticulate, but with little tufts of setules on posterior 

 margins of posterior segments. Maxilliped with minute rudimentary 4th palpal joint. 

 Antenna 1 , flagellum 5 -jointed, with sen- 

 sory setae, accessory flagellum3-jointed, 

 terminal joint minute. Antenna 2, flagel- 

 lum 7-jointed, each joint except the last 

 with a spine or spiniform calceolus. 

 Gnathopod 1 stout, 2nd joint somewhat 

 flask-shaped, expanding distally, suture 

 between 4th and 5th joints not dis- 

 tinguishable, 5th very short, 6th very 

 large, oval, palm oblique, not defined 

 except by the row of very regular pali- 

 sade-like cylindrical spines, which are 

 apically bifid or truncate. Other appen- 

 dages resembling those of $ . 



Remarks. An interesting extension 

 of the habitat of a species originally collected by the ' Challenger', and since then only 

 by the ' Valdivia'. The ? is twice as large as the Challenger specimens, but agrees in 

 all respects except that the flagellum of the antenna is 9-jointed. 



Distribution. Kerguelen.

Schellenberg, 1931, p. 61, fig. 32. 



Occurrence: 1. St. 51. Falklands. 1 c? 5 mm., 1 ovig. $ 4-5 mm. 



2. St. WS 76. Falklands. 4 $$ 3-5-4-5 mm., picked out of sand. 



Description. Eyes invisible. Antero-inferior angle of head produced in an acute 

 point curving forwards. Side-plates 1-3 narrow, 4 as in elegans (Sars, pi. xlvii, as 

 norvegica). Pleon segment 3 dorsally gibbous as in Haustorins; postero-inferior angle of 

 pleon segment 2 quadrate with a minute point, of 3 produced in a large upturned hook- 

 like acute point, the margin above only slightly convex. Telson a little longer than wide, 

 cleft to base, each lobe with an apical spinule, and two lateral setules.
