CANDONA. 



Miill. pt.). A genus of Entomostraca, order 

 Cladocera, family Lynceidae. 



Char. Carapace ovoid ; beak blunt, di- 

 rected forwards or slightly downwards j ab- 

 domen long, slender, tail-like, extremely 

 flexible, and serrated. 1 species : 



C. macrourm (PL 20. %. 4). Carapace

CAMPTOUM, Link. A genus of De- 

 matiei (Hyphomycetous Fungi), allied to 

 Arthrinium. C. curvatum, Lk. (Arthrinium 

 curvtitum, Kze.) grows in tufts of very slen- 

 der filaments, bearing very minute, curved 

 spores, upon Scirpu* si/lvaticus.

CAMPYLODIS'CUS, Ehr. A genus of 

 Diatomaceas. 



Char. Frustules single, free, disk-shaped ; 

 disk curved or twisted (saddle-shaped) ; fur- 

 nished with mostly radiate markings, which 

 are frequently interrupted. Aquatic and 

 marine. 



The markings are costfe or canaliculi, 

 forming minute canals between the internal 

 cell-membrane and the surrounding fluid 

 (Smith). 



Smith describes 9 species (British) ; Ra- 

 benhorst describes 28 European species, and 

 enumerates 27 foreign and fossil species. 



C. costatus, Smith (PI. 1 6. fig. 16). Valves 

 circular j radii 30-40, extending about half- 

 way to the centre, which is minutely 

 punctate ; diameter 1-270" ; aquatic. 



C. spiralis, Smith. Outline of front view 

 resembling a figure of 8 ; valves elliptical j 

 radii about 60, nearly parallel and trans- 

 verse ; length 1-160" ; aquatic. 



C. dypeus, Ehr. (PI. 25. fig. 18). Valves 

 suborbicular, exhibiting a circular and a me- 

 dian transverse hyaline line ; radii broad, 

 interrupted in the middle, which is punctate ; 

 length 1-200" ; aquatic and fossil.

CAMPYLONE'IS, Grun. A genus of 

 Diatomacese, family Entopyleae. 



Char. Frustules scutelliform, adnate, 



transversely arcuate ; valves heterogeneous 

 the inferior costate, the superior cribroso- 

 punctate ; nodules absent.

 nus of marine Infusoria, family Oxytrichiua. 



C. paradoxus (PI. 51. fig. 29). With six 

 posterior setse, and eight posterior feet, six 

 on the right and two on the left side. Re- 

 markable for its bounding leaps, which 

 make it very difficult of observation.

 ding some Dicrana and Grimmice of older 

 authors.

CANDA, Lamx. (Cellularia part, John- 

 ston). A genus of Infundibulate Polyzoa 

 (Bryozoa), of the suborder Cyclostomata, 

 and family Cellulariidae. 



Distinguished by the jointed, branched, 

 erect polypidom, the flat, linear branches 

 with the cells on one plane, and the cells 

 having a vibraculum in a notch on the outer 

 side but no avicularium at the upper angle. 



Placed with Scrupocellaria by Hincks. 



C. reptans (Cellularia rept., Johnston) 

 (PI. 41. figs. 5, 5 c, and 5 d). Orifice oval, 

 with 3 or 4 marginal spines, and a stalked 

 operculum with a lobed lamina. Common.

 pseudopodial pores along the base of its last 

 chamber.
