Clavella obesa Richiardi (1880, p. 152) was named but never de- 

 scribed or figured. It probably belongs to the genus Hatschekia and 

 not to Clavella. 



Anchorella ovalis Kr0yer (1837, p. 289, pi. 3, fig. 6) belongs to the 

 new genus ClaveXlisa (see p. 696). 



Anchorella paradoxa van Beneden (1851, p. 117, pi. 6, fig. 1) is here 

 referred to the new genus Clavellopsis (see p. 687). 



Anchorella quadrata Bassett-Smith (1896, p. 15, pi. 4, fig. 5) is 

 probably a Clavella and is retained m that genus, although it is veiy 

 meagerly described. 



Clavella rohusta Wilson (1912, p. 96, pi. 8, figs. 73 to 78) has bira- 

 mose second antennae and short posterior processes similar to those 

 of Kr0yer's Anchorella laciniata. It can not, therefore, remain in 

 the genus Clavella, but must be transferred to the new genus Clavel- 

 lopsis (see p. 688). 



Anchorella rugosa Kr0yer (1837, p. 284, pi. 3, fig. 14) is not a Cla- 

 vella and is made the type of the new genus Clavellodes (see p. 690). 



Anchorella sargi Kurz (1877, p. 393, pi. 25, figs. 5, 6, 29, 51, 52) is 

 also not a Clavella, and is transferred to the new genus Clavellopsis 

 (seep. 687). 



Clavella sdaenae Brian (1906, p. 119, pi. 10, fig. 2; pi. 20, figs. 13, 

 14) is probably identical with Heller's Anchorella sciaenophila as 

 Brian suggests. The presence of four posterior processes and the 

 details of the antennae and mouth parts indicate that it should be 

 transferred to the genus Brachiella. Here also the rriale must 

 finally decide where the species belongs. 



Anchorella sciaenophila Heller (1865, p. 243, pi. 24, fig. 8) is here 

 transferred to the genus Brachiella, as just stated (see p. 703). 



Anchorella scomhri Kurz (1877, p. 403, pi. 25, figs. 12, 35, 41) is 

 not a Clavella and is referred to the new genus Clavellisa (seep. 694). 



Anchorella stellata Kr0yer (1838, p. 142, pi. 3, fig. 5) is probably a 

 Clavella, and may be left there until further data can be obtained. 



Clavella strumosa Brian (1906, p. 112, pi. 9, figs. 4 to 7) is not a 

 Clavella and is referred to the new genus Clavellopsis (see p. 687). 



Anchorella triglae Kurz (1877, p. 404, pi. 35, figs. 13 to 15) was first 

 described by Glaus as a Brachiella (see p. 702), and was transferred by 

 Kurz to AncJiorella. The male shows conclusively that it belongs 

 where Glaus placed it. 



Anchorella urolophi Kr0yer (1863, p. 304, pi. 16, fig. 10) also pre- 

 sents marked exceptions to the Clavella characters. The second 

 antennae are biramose, and there is a two-jomted abdomen with well- 

 developed anal laminae. These furnish serious reasons for exclud- 

 ing it from the genus Clavella, but they do not tell us where it ought 

 to be placed.
