POLYCHAETOUS ANNELIDS FROM PHILIPPINE SEAS. 625 



only 16 setigerous somites are present, it is impossible to tell 

 how many there would be in a complete specimen. This form is 

 doubtfully placed in the genus MeUnna, a^s the presence of two 

 kinds of tentacles suggests that it may belong to a new but similar 

 genus. The present interpretation is based upon the marked re- 

 semblance in form between this specimen and Marenzeller's M. 

 adriatioa. 



Type collected at station D5513, Camp Overton Light, Mindanao, 

 505 fathoms, gray mud and fine sand bottom, temperature 52.8°. 



Family CAPITELLIDAE. 



Genus NOTOMASTUS Sars. 



NOTOMASTUS LATERICEUS Sars. 



Wotomastus latericeus Sars. Pauvel (1014), p. 250, pi. 10, fig. 14: pi. 22, 

 fig. 20. 

 Specimen incomplete posteriorly. Differing slightly from Fauvel's 

 description in the length of the peristomium — a condition probably 

 due to differences in preservation. Proboscis not extruded. 



Collected at station Do 100, Corregidor Light, off Luzon, 35 fathoms, 

 gray sand bottom. 



Family OPHELIIDAE. 



Genus AMMOTRYPANE Rathke.

Type.— Cat. No. 18962, U.S.N.M. Specimen, 70 mm. in length: 

 width anteriorly, 3 mm.; greatest width (through middle region), 7 

 mm.; width posteriorly, 5 mm. As the post-middle region of the 

 body is distorted by drying, it is impossible to determine how far 

 posteriorly the broad region extends.
