but the genus Anchorella can not possibly include uncinata and its 

 relatives, as has been the common usage. 



Synonyms. — To this illegitimate genus Anchorella has been referred 

 indiscriminately a heterogeneous collection of more than 50 species, 

 among wliich we must recognize at least three new genera. These 

 species furnish one of the most convincing proofs that could be given 

 of the lax methods adopted in dealing with the Lernaeopods. There 

 are 16 species which are mere names, having never been either de- 

 scribed or figured, one the data with reference to which do not justify 

 us in locating it anywhere, 7 which can be located with probability, 

 but not certainty, and 18 which must be transferred to other genera. 

 This leaves only 17 out of the original 52, and to them are added 9 

 others which are new to science. 



Anchorella carusi, cJiarads, clava, crassa, elongata, lichiae, simplex 

 subtilis, and tenuis were simply named in RichiarcU's ''Catalogo 

 sistematico dei Crostacei." Brian afterwards described (1906, p. 113) 

 and figured (pi. 10, fig. 5) Richiardi's characis, so that it can be 

 definitely located in the genus Clavella, where he placed it. He also 

 mentioned the other species, but without describing or figuring them. 



Anchorella adunca has been noted above. 



The following four species were described and figured by Kr0yer 

 (1863), Anchorella agilis (p. 300, pi. 16, fig. 2); A. angulata (p. 293, 

 pi. 15, fig. 3) ; A. denticis (p. 296, pi. 16, fig. 4) ; A. pagelli (p. 295, pi. 16, 

 fig. 3). The last two appear in Brian's "Copepodi parassiti dei pesci 

 d'ltalia," but his additions to Kr0yer's descriptions consist of a few 

 details with reference to the maxilHpeds. 



We have no data on the mouth parts, the antennae, or the male of 

 either of the four species. A. agilis has been found by several col- 

 lectors off the coast of Greenland (see Stephensen, 1913, p. 339), but 

 nothing has been added to Kr0yer's meager description. The four 

 probably belong to Clavella, but there can be no certainty until these 

 additional data are forthcoming. 



Anchorella (Lernaea) anomala was described and figured by Abild- 

 gaard (1794, p. 57, pi. 6, fig. 2), who of course placed it in the genus 

 Lernaea. Milne Edwards said of it: 



Le Lernea anomala d'Abildgaard parait appartenir aussi d ce genre [Anchorella], 

 mais diff^rerait de toutes les especes precedentes pax la longueur considerable de 

 I'organe d'adh&ion, et par I'existence d'un renflement en forme de nojud a I'ex- 

 tr^mite ant^rieure du thorax (1840, p. 520). 



But of course this is not enough to identify the species and it also 

 must await fm-ther details. 



Anchorella appendiculata and A. appendiculosa (Kr0yer, 1863, 

 pp. 305 and 306, pi. 16, figs. 6 and 7) were each founded on a single 

 specimen and no others have ever been obtained. The details given
