Codonella Haeckel. 
10. C. Ostenfeldii Schm. 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 .0bo- 
vate, with rounded or subacute end, covered by 
agglutinated foreign bodies which conceal its reti- 
culated structure. 
Total length: 125—204 np. 
Length of proboscis: 77—119 p. 
Breadth of proboscis: 38—41 p. 
Breadth of apical part: 53—56 p. 
Diameter of perforations: about 7 pm. 
This peculiar species is related to Codonella 
morchella Cleve, from which it is easily distin- SET 
guished by the perforated proboscis. The length Fig 4. Codonella

The shape of the apical part is not always 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. 
1) Qwing to the perforation of the probosecis 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. 9. D. templum
