are sufficient to show that these species do not belong to the present 

 genus. Tlie four posterior processes, the second antennae, and the 

 maxilUpeds show a greater affinity with Brachiella than with Clavella, 

 and accordingly the species are transferred to that genus. Kr0yer 

 claimed to have found a male of appendiculata, but put a question 

 mark after the sex. So far as can be determined from his figures and 

 description this ''male" was simply a piece of the skin of the host 

 and was not even anything alive. 



AnchoreUa canthari Heller (1865, p. 242, pi. 24, fig. 6) almost cer- 

 tainly belongs to the genus Clavella. Heller does not give very many 

 details in his brief description, but the additional data and the 

 excellent figures of T. and A. Scott (1913, p. 224, pi. 69, figs. 1 to 3) 

 are sufficient to locate it accurately. 



AnchoreUa centrodonti van Beneden (1870, p. 43) was figured (pi. 2, 

 fig. 5), but not described, and as far as the figure shows, appears to be 

 a synonym of imcjelli. 



AnclioreUa dilatata Kr0yer (1863, p. 302, pi. 15, fig. 2) shows several 

 exceptional characters, notably the biramose second antennae and 

 the body lobes on either side of the abdomen. If the details be just 

 as Kr0yer has described them, it differs considerably from Clavella, 

 but can not be estabhshed elsewhere on our present knowledge. 



AnchoreUa emarginata Kr0yer (1837, p. 287, pi. 3, fig. 7) is here 

 referred to the new genus Clavellisa (see p. 694). 



Aiichorella fallax Heller (1865, p. 241, pi. 24, figs. 4 and 5) is here 

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



AnchoreUa hosiilis Heller (1865, p. 243, pi. 24, fig. 7) is certainly 

 not a Clavella, and probably belongs to the genus Brachiella (see p. 702), 

 but the male is needed for positive determination. 



AnchoreUa intermedia Quidor (1906, p. 29, pi. 3, figs. 37 to 44) has 

 biramose second antennae and slender maxilhpeds, not reinforced. 

 The male also corresponds mth that of the genus Clavellodes but 

 differs markedly from a Clavella male. The species, therefore, 

 should be placed in the new genus Clavellodes (see p. 690). 



AnchoreUa laciniata Kr0yer (1863, p. 308, pi. 16, fig. 18) is here 

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



AnchoreUa lagenula Guerin (1817, pi. 9, fig. 5) is a synonym for C. 

 uncinata. 



AnchoreUa lizae Kr0yer (1863, p. 294, pi. 16, fig. 11) belongs to the 

 genus Naohranchia (see p. 660). 



Clavella macrotrachelus Brian (1906, p. 116, pi. 21, figs. 1 to 4) is not 

 a Clavella, as is shown by the male, and is referred to the new genus 

 Clavellodes (see p. 690). 



AnchoreUa microcephala was named by Nordmann (1832, p. 107), 

 but was never described or figured.
