“Amphitrite edwardsi (Quatrefages).

St. WS 80. 14. iii. 27. 50° 57' 00" 5, 63° 37' 30" W. From 5o° 58' 00" S, 63° 39' 00" W to 50° 55' 30" S, 63° 36' 00" W. 152-156 m. Gear OTC. Bottom: fine dark sand. One specimen.

 

St. WS 81. 19. iii. 27. 8 miles N 11° W of North Island, West Falkland Island. From

 

51° 30' 00" 5, 61° 15’ 00" W to 51° 30' 30" S, 61° 10' 00" W. 81-82 in. Gear OTC. Two specimens.

 

St. WS 97. 18. iv. 27. 49⁰ 00’ 30" S, 61° 58' 00" W. From 49° 00’ 00" S, 62° 00’ 00" W to 49° 01' 00" S, 61° 56' 00" W. 146-145 m. Gear OTC. Bottom: sand, gravel and stones. Four specimens.

 

REMARKS. The largest specimen measures 45 mm. by 6 mm. for 48 chaetigers. It is incomplete posteriorly. The thorax is thick and dorsally arched. There arc no eye spots. There are large lateral flaps on the 2nd and 3rd segments and a small one on the 4th. There are 11 ventral gland shields. Each of the three pairs of gills (Fig. 79, a) consists of a pair of stout and richly branched trunks. The nephridia extend from the 3rd to the 12th segments. There are 17 thoracic notopods. The dorsal bristles have distinct borders and a long denticulated apex (Fig. 79, b) . The double rows of hooks (Fig. 79, c) extend from the 7th to the 16th uncinigers. The hooks have about six rows of teeth above the main fang. Posteriorly the abdominal tori are gradually transformed into narrow pinnules.

 

I have compared these specimens with some examples from St Vaast named by Fauvel and, except in the matter of size and in the fact that in the European specimens the nephridia extend from the 3rd to the 11th segments, while in the southern examples they extend from the 3rd to the 12th segments, I can find nothing to distinguish them. The tube is a plain structure with walls of mud.

 

This species would fall within Hessle's genus Neoamphitrite, which Fauvel rejects.”
