Bugulella, Verrill, 1879, Amer. J. Sci. Arts, (3) xvii. p. 472. — Genotype (the onl}' 
species), BugideUa fragilis, Verr., n. sp., described as allied to Bicellaria and 
perhaps to Brettia. 
Bugulina, Gra)', 1848, p. 114. — Genotype (the only species), Bugulina avicularia 
{Sertularia avicularia, L., s. str.). The form indicated by Gray is the biserial 
species of Ellis (1755, p. 36, pi. 20. figs, a, A), to which the trivial name of 
Linnseus is now restricted. See Bugula, of which this genus is a synonym. 
Bugtilopsis, Verrill, 1880, Proc. U.S. Nat. Mus. ii. (1879), p. 190.— Genotype, selected 
by the author, Bugtdopsis peacMi {Gellularia peacliii, Busk, 1851, A.M. N. H. 
(2) vii. p. 82). Synonym of Tricellaria, Fleming, 1828. 
Gaherea, Lamouroux, 1816, p. 128. — Genosyntypes, C. pinnata and C. dicJiotoma, 
Lamx., n. spp., both from " Australasie." Genolectotype, C. diehotoma, see 
Schweigger, 1819, Tab. 9 ; 1820, p. 430 ; and Gray, 1848, p. 147. 
Caberiella, Levinsen, 1909, pp. 134, 135. — Genotype (the only species), Caheriella 
benemunita {Menipea benemunita, Busk, 1884, p. 19). Synonym oi Amastigia, 
Busk, 1852. 
Caheroides, Canu, 1908, Ann. Paleont. iii. p. 87 (83, sep.). — Genot3'pe, selected by 
the author, Oaberoides canaliculata, Canu, n. sp. The genus is described as 
resembling Caberea and also members of the Lepralioid series (Hippoporinse). 
Oamptoplites * , n. gen. — Genotype, Camptoplites bicornis (Bugida hicornis, Busk, 
1884, p. 40). I propose this genus for Sect. /5 of Bugida as given in Busk's 
' Challenger ' Eeport, 1884, p. 37, with the following diagnosis : — 
Zoarium stalked, the stalk prolonged basally into an attaching tuft of 
rootlets. Zooecia biserial or pluriserial, narrow proximally, the opesia 
occupying most of the expanded distal portion. Proximal ends of the 
zooecia not forked. Avicularia borne on long, flexible stalks, which usually 
exceed the head of the avicularium in length. Operculum distinguishable, 
ovicells well developed. 
The peculiarities of the avicularium and the absence of a forked proximal 
end in the zooecia seem to justify geueric separation for this assemblage of 
forms, which are characteristic of abyssal depths and of the Antarctic area. 
In addition to the type-species and B. reticulata, described bj' Busk in his 
original account, the following species are referable to Gamptoplites : — 
Bugula tricornis, "Waters, 1904, '' Belgica" Bryozoa, p. 23 ; and the following ' 
species described by Kluge (1914) : — Bugula bicornis, vars. (pp. 619-624), 
B. areolaia (p. 627), Bugula sp., var. variospinosa, nov. (p. 628), B. multi- 
sjnnosa (p. 628), B. retiforniis (p. 629), B. lewaldi (p. 630), B. gigantea (p. 630), 
jB. angusta (p. 631), B. abyssicola (p. 632), and B. lata (p. 634), KL, n. spp. 
Ganda, Lamouroux, 1816, p. 131. — Genotype (the only species), Cancla arachnoides, 
Lamx., n. sp. 
* Kn/iTTTos, flexible ; ottXittjs, an ormed man ; in allusion to the long, flexible .stalk of the 
Avicularium. The genus is masculine.
