"Tabanus parvus, n. sp/' (p. 69).— In size and general 

 appearance, as also in the width of the front, this small 

 species closely resembles T. anellosus, Summers (Ann. & 

 Mag. Nat. Hist. ser. 8, vol. x., Aug. 1912, p. 226), the 

 typical series of which was also taken at Port Darwin by 

 i)r. C. L. Strangman, the discoverer of Tabanus parvus at 

 the same place. The latter species can, however, be distin- 

 guished from T. anellosus by the expauded portion of the 

 third joint of the antenna being shorter and deeper, by the 

 terminal annuli of the same joint being tawny-ochraceous 

 like the rest of the joint, instead of dark brown, by the 

 existence of a long appendix to the anterior branch of the 

 third longitudinal vein, and by all coxse, femora, and tibise 

 being ochraccous-butf, whereas in T. anellosus the coxae are 

 grey, all the femora greyish clove-brown, and the front 

 tibiae clove-brown except at the base. Judging from an 

 examination of the paratype of T. parvus kindly presented 

 to the National Collection by Mr. Taylor, the description of 

 the coxa;, femora, and tibia; of this species as "clove-brown" 

 is extremely misleading.

The following report, which includes the Nephtliydidte, 

 Phyllodocidie, and llesiunida', is a continuation of that begun 

 i)y'Mr. William Small, M.A., B.Sc, in 1912 (Ann. & Mag. 

 >;at. Hist. (8) vol. x. p. 1(55, iU12). 



The Nephtliydida; are well represented, and out of the ten 

 species accounted British by Prof. I^l'lntosh, six have been 

 found to be present in the North Sea. The Phyllodocidie 

 are but sparsely represented by a single species, whde the 

 Ilesionida; siiow re|)resentatives of two genera out of the tour 

 that are Jiritish. They occur in numerous hauls at various 

 dtplhs and at various stations raiigin^^ from shallow water
