SABELLIDES AND SERPULIDES 227 



(37) PROTIS Ehlers 1887.

 in 860 fms. 



Uncini similar to Eupomatus.

15. Branchial lobes not spiral. 



(38) PSYGMOBRANCHUS PMHppi 1844. * 



Type, P. protensus (Gmelin) Claparede 1870, figures. Mediterranean

Type, P. nigroanntilata Templeton 1835, figures, -f Kinberg, 1866. 

 Black River, Island of Mauritius, Indian Ocean. 

 Uncini unknown. 



(40) PROTULA Risso 1826. 



Type P. rudolphi Risso 1826, as first species. Mediterranean Sea at 

 Nice in about 3 feet. 



Uncial plates irregular in outline, with numerous very fine teeth on 

 the face, the lowest one very long and fang-like. 



(41) PROTULOPSIS Saint-Joseph 1894.* 



Type, P. intestinum (Lamarck 1818, as Protula] Saint-Joseph 1894, 

 figure. Seas of Europe (Triest and Naples). 

 Uncini unknown. 



1 Psygmobranckus caecus Claparede 1870 has uncini with few coarse teeth like 

 Eupomatus, and is probably referable to Protis^ although Claparede suggested its 

 resemblance to Salmacina. Psygmobranchus multicostatus Claparede 1870 has 

 uncini more nearly like Serpula, so that it should be referred to Salmacina. 



1 Anisomelus luteus Templeton 1835, from the figures, shows characters placing 

 it with the Terebellacea as designated by Quatrefages (1865), rather than with the 

 Serpulacea as given by Morch (1863). There are four pairs of branchiae, very 

 long and very short, below which, on the thorax, are 6 filaments similar to those 

 found on Trickobranchus glacialis Malmgren 1865, figures. 



Saint-Joseph (1894) makes Protula intestinum Lamarck, an abdominal seta of 

 which he figures, the type of a new subgenus, Protulopsis. There is, however, 

 considerable uncertainty in regard to the other characters, as no figures have 

 been found. Excellent figures are given by Fischli (1900) of his soecies Protu- 

 lopsi* nigra-nucka ; the uncini are similar to Hyalopomatopsis.
