"VITI. — The Pycnogonida collected hy the ^ Gauss ^ in the 

 Antarctic Regions, 1901-3. — Preliminary Report. Bj 

 T. V. Hodgson. 



I REGRET tliat I have been so long in working out tlie 

 collection of tlie Pjciiogonidia made by the German Antarctic 

 Expedition ('Gauss') in 1901-3. I hope that the final 

 drawings and memoranda will be completed in the course of 

 a few weeks at tlie outside, but, in order to secure the priority 

 of description in certain species, I desire to publish the 

 following preliminary report. The collection is a fairly rich 

 one, and while it shows certain strong relations to those of 

 other expeditions, it is, on the other hand, quite distinctive. 

 It contains three new genera and twenty new species from 

 the Antarctic and two more from tropical and temperate seas, 

 as follows : — 



Colossendeis glacialis. 

 Colossendeis glacialis, Hodgson, Pycnogonida, ' Discovery/ 1907. 



A single specimen of this species was taken in the ' Gauss * 

 winter-quarters. 



NOTOENDEIS. 



This new genus is established to mark the difference be- 

 tween the large and well-known Colossendeis and closely 

 allied species. 



Body perfectly segmented, with short and distinctly sepa- 

 rated lateral processes and with well-developed eyes. 



Proboscis very large. 



Palps nine-jointed. 



Oviger ten-jointed, with a terminal claw. 



Notoendeis germanica. 



The proboscis is as long as the body, and the terminal 

 joints of the palps are as 8 — 5'5 — 4*5. 

 The body is robust and smooth. 

 Winter-quarters, 400 m. 



Pipetfa australis. 



The genus was established by Dr. Loman for a tropical 

 species, and now includes an antarctic species taken near the 

 ' Gauss ' winter-quarters in 2450 m.
