Annelés,’ a nereid which he called Nereis heterocheta, from Java. 
Grube (1870, p. 312) states that this description refers to Tylo- 
rhynchus chinensis. Quatrefages’ description is not sufficient 
for identification, but as Grube personally examined Quatrefages’ 
material in the Paris Museum, there is no reason for hesitation 
in accepting this record as a good one. As Quatrefages’ de- 
scription was very inadequate, and was accompanied by no figures, 
I have not thought it necessary to give his name preference to 
that of Grube. 
Genus CeraTocEPHALE Malmgren, 1867. 
Characters.—As for Tylorhynchus, except that :— 
Hyes are absent. 
The neuropodium bears a well-developed ventral ligule 
as well as the setigerous lobe. 
The neuro-cirri are double, the two cirri arising from a 
common base. 
Range.—The North Atlantic (Scandinavia: Malmgren, Heinen, 
Levinsen, etc.); Eastern North America (Gulf of St. Lawrence : 
McIntosh ; Massachusetts: Verrill). 
Only one species has been satisfactorily described, viz., C. loveni 
Malmgren, 1867, from the Scandinavian waters. Those from 
the American side may prove to be identical with this, although 
Verrill (1879) named his specimens C’. websteri, without, however, 
giving a satisfactory diagnosis, and without figures.
