Codonella Haeckel. 
10. C. Ostenfeldii Sclim. n. sp.*) 
House clavate; proboscis longer than apical 
part, cylindrical or slightly narrowed towards 
the mOuth , with numerous as well transversely as 
spirally arranged perforations; apical part obo- 
vate, with rounded or subacute end, covered by 
agglutinated foreign bodies which conceal its reti- 
culated structure. 
Total length: 125 — 204 p. 
Length of proboscis: 77 — 119 p. 
Breadth of proboscis: 38—41 p. 
Breadth of apical part: 53 — 56 p. 
Diameter of perf orations: about 7 p. 
Tilis peculiar species is related to Codonella 
morchella Cleve, from wliich it is easily distin- 
guislied by the perforated proboscis. The length Fig 4. Codonella

The sliape of the apical part is not ahvays obovate as figured 
by Cleve; sometimes it is ovate as in C. Ostenfeldii or also it 
may be quite globose. I saw specimens, where the proboscis was 
covered by agglutinated foreign bodies. 
*) Owing to the perforation of the proboscis some authors should per¬ 
haps refer this species to the genus Dictiocysta ; I prefer to restrict 
the extension of that genus to forms, where the proboscis has but 
one or a few rows of large perforations («Windows«) f. i. D. templum
