POLYCHAETE WORMS, PART 1 133 



Genus Brania Quatrefages, 1866 



Grubea Quatrefages, 1866, preoccupied by Diesing (1858, Vermes, Trematoda). 



Tj'pe (herein designated): Grubea clavata (Claparede, 1863). 

 Grubiosyllis Verrill, 1900; new name for Grubea Quatrefages, preoccupied. 



Type (moiiotypy) : Brania pvsilla (Dujardin, 1851). 



Both species are tiny, slender, threadlike, cylindrical. Prostomium 

 suboval, wider than long; median antenna attached posteriorly 

 between posterior pair of eyes; lateral antenna anterior on prostomium; 

 palps large and prominent, fused basally, more or less free distally. 

 Tentacular segment more or less distinct, with 2 pairs tentacular 

 cirri similar to antennae. Antennae and dorsal cirri subulate, wider 

 basally, tapering to more slender tips; dorsal cirri extending slightly 

 beyond the setal tips. Ventral cirri digitiform, extending about to 

 tips of setal lobes. 



Key to the New England Species of Brania 



1. Parapodia with compound setae with distal blades shorter to longer, with tips 

 finely bidentate. Prostomium with a pair of small ocular spots near the 

 lateral antennae in addition to the four larger eyes (fig. 356). With dorsal 



cirri on setiger 2 B. clavata 



Parapodia with compound setae with distal blades short, subequal, with tips 

 entire (fig. 35/i). Prostomium without ocular spots. Without dorsal cirri 

 on setiger 2 . , B. wellfleetensis 



Brania clavata (Claparede, 1863)

Description. — Length up to 4 mm., width up to 0.3 mm., segments 

 21 to 35. Prostomium with 2 pairs of ej^es, anterior lateral pair larger 

 with large lenses; an additional minute pair of ocular spots near the 

 lateral antennae; palps fused nearly to the obtuse rounded tips, 

 grooved ventrally. Upper pair tentacular cirri about same length 

 as the median antenna, lower pair about half as long (may easily be 

 overlooked). Parapodia with setae of 2 kinds: Upper simple pointed 

 one; compound setae with distal blades shorter to longer, finely 

 bidentate, slightly hooked; posterior segments with upper and lower 

 simple setae. Anal cirri 2, fusiform, may be longer than dorsal cirri.
