ANNKLIDA. 
Genus — SEllPULA, Linnceus, 1758. 
(Systema, Eil. X, 1758, p. 78G.) 
Serpula TONGOivoKExsis/ sj). noc. 
(PI. I, Fig. 11.) 
8p. Char . — Tubes sul)cylindrical, noncarinate, as broad as bigb, or 
even a little broader tban lii^b, attached wholly to tlio foreign body affording 
them support, or intermingled and superimposed on one another, but without 
a trace of intercoil ing, or formation of a helix, and passing out in free ends ; 
when separate, running parallel to one another in the same plane, and in 
contact laterally ; when intermingled forming loosely aggregated groups. 
Section oval. Surface nearly smooth in places, or transversely wrinkled and 
somewhat corrugated in others. 
Ohs. — The late ]\ir. Charles Moore recorded'^ a Serpula from the 
"Wollumbilla beds of the Queensland Rolling Downs Rormation, which he 
referred to S. intestinalis, Phill.,^ but without description or figure. In 
Phillips’ fossil the tube seems to spring from a loosely coiled nucleus, giving 
one the impression of a solitary rather than a communal form as in the 
present instance. The latter is also distinct from an allied form, S. tenui- 
carinata, M. and 11.,^ from the Cretaceous of Dakota and the Upper Missouri, 
in which the tubes are carinate and separate. The tubes are attached to the 
outer surface of tlie shell of MaccouelUt corhiensis, Moore, sp. 
The nearest ally to this form 1 have been able to find is S. semicoalita, 
AVhiteaves,'' from the Cretaceous rocks of Manitoba, but differs in possessing 
tubes of a less intermingled character.
