 matiei (Hj^phomycetous Fungi), allied to 

 Arthrininm. C. ci/rvatum, Lk. (Arthrinium

CAMPY LODIS'CUS, Ehr.— A genus of 

 Diatomacefe. 



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 costae or canalicidi, 

 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 (PL 16. fig. 16). Valves 

 circular ; 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 

 resembhng a figure of 8; valves elliptical; 

 radii about 00, nearly parallel and trans- 

 verse; length 1-160" ; aquatic. 



C. clypeus, Ehr. (PI. 2o. fig. 18). Valves 

 suborbicidar, 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.

transversely arcuate ; valves heterogeneous 

 — the inferior costate, the superior cribroso- 

 punctate ; nodules absent.

 nus of marine Infusoria, family Oxytrichina. 

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

 posterior setae, 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.

 A genus of Leptotrichaceous Mosses, inclu- 

 ding some Dicrana and Grimmice of older 

 authors.

CANDA, Lamx. (CeZ/M/a/va part, John- 

 ston). — A genus of lufundibulate Polyzoa 

 (Bryozoa), of the suborder Cyclostomata, 

 and family Cellulariidse. 



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. rt'pfans (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.
