190 THE ANNELIDA POLYCHAETA. 



H. pantherina) as found on the coasts of France and at the Cape Verde 

 Islands respectively, agree with my Mediterranean specimens in this regard, 

 so that I think the character must be regarded as constant. Marenzeller's 

 figure of the seta (Sudjapan. Anneliden, 1879, pi. 3, f. 4) of his H. reticulata 

 (Cf. Plate 22, fig. 13) shows a form different from that of the real H. splendida, 

 as I believe, and that species seems therefore valid. The figures given by 

 Gravier (Nouv. arch. Mus. hist. nat. 1900, ser. 4, 2, p. 175, 177, fig. 43-45) 

 of the seta of his H. ehlersi {Cf. Plate 22, fig. 14) also represent a clearly different 

 form, and I think the species will be found to be valid in spite of an error as to 

 a principal character upon which the separation was originally based.

Locality. Society Islands: Papeete. Shore. 9 November, 1899. One 

 specimen. 



The species is also known to occur in the Samoan and Philippine regions. 



Leocrates anomalus, sp. nov.^ 



The body is strongly fusiform and somewhat more narrowed caudad than 

 cephalad. It is widest in the region of the eighth and ninth somites. The 

 somites are shortest at the ends of the body. No dividing lines between somites 

 are indicated on the dorsal surface. Length 17 mm.; greatest width of body 

 proper, 3.25 mm. 



The original color rather uncertain. At present the type is of a pearly 

 yellowish grey color, with the dorsum somewhat dusky caudally and laterally 

 and without markings. The venter with a pale median line, bordered on each 

 side by a dark line. 



The prostomium in the type somewhat shrunken, appearing subquadrate 



' Vco/jaXos, anomalous.
