PHYLLODOCE SP. Ill 



boscis shows six rounded principal longitudinal ridges which are segmented by- 

 fine transverse sulci. Some minor and mcomplete intermediate ridges may 

 also be seen. 



Locality. Paumotu Archipelago : Fakarava. Fringing reef. 12 October, 

 1899. One specimen. 



The general form of the body in this species, broad anteriorly and strikingly 

 narrowed and geophiloid in the middle and posterior regions, is a conspicuous 

 feature. The general structm-e and form of the prostomium and proboscis 

 are also distinctive characteristics, which, in connection with the form of the 

 parapodia and the body-form, serve to separate the species from related forms. 

 Kinberg's description of his P. gracilis, from the Society Islands, is too brief 

 for certain identification. His words (Ofvers. K. vet. akad. Forh., 1865, no. 4, 

 p. 240) "Lobus cephahcus rotundatus" do not apply to the present species; 

 and the further statement "branchiae foliosae superiores o vales elongati" is 

 likewise scarcely apphcable. From the more recently pubUshed figures Augener 

 thinks it probable that his ovalifera may be gracilis Kinberg (Michaelsen & 

 Hartmeyer, Fauna Siidwest-Australiens, 1913, 4, Uef. 5, p. 127). If so, the latter 

 is then certainly mdely different from the form above described. 



Phtllodoce medipapillata Moore. 



Proc. Acad. nat. sci., Philad. 1909, p. 237, pi. 7, fig. 3, 4. 



Locality. Panama. March, 1891. One specimen. 



Pre\aously known from Monterey Bay and San Diego, CaUfornia. 



The specimen from Panama is 92 mjn. long and is composed of 212 somites. 

 It agrees weU mth Moore's description, though the styles of the notocirri on 

 the whole appear to be broader and perhaps more asymmetrical. The eyes are 

 somewhat elliptic rather than circular. The proboscis is not at aU extruded so 

 that its characters were not compared. 



Phyllodoce sp. a. 



The specimen representing this form has at some time been completely 

 dried, has lost all its setae, and is otherwise in such poor condition that definite 

 identification seems impracticable. The specimen is about 125 mm. long. 

 Near the anterior end it is 3.25 mm. wide, inclusive of the parapodia. It narrows 

 continuously caudad and in the middle and posterior region becomes very
