Polychaeta 25 B 
Ampharete eupalea, n. sp. 
Type specimen.—Cat. No. 31, Victoria Memorial Museum, Ottawa. 
One specimen. 
The branchie are large and equal. They form a continuous straight line 
across the dorsum, the two mesal ones in contact, leaving no indication of an 
hiatus between the two groups. 
The palez on each side are arranged in a strongly curved series forming 
about two-thirds of the circumference of a circle. In the type they number 
twenty-two or twenty-three in each series. The pales at the mesal end of the 
series on the dorsal side of the curve are much reduced in size. Each palea is 
acutely pointed distally, the tip not truly mucronate, though with a slight 
tendency toward that condition. The tip is curved gently toward the centre 
of the circle limited by the series. (See Pl. V, fig. 6.) 
The thoracic’ notopodial sete narrowly limbate and finely tipped as usual. 
The uncini of the type are obviously larger than those of the two preceding 
species. There are five teeth in each series, plate slightly indented at the end, 
the corners rounded. (See Pl. V, fig. 7.) pute 
The type is incomplete, embracing only the anterior region of the thorax 
ten setigerous somites being present. The diameter is 3 mm.
