1898.] FEOM EOTUMA AND FUNAFUTI. 471 



7. Physcosoma tarians Kef. 



One specimen from Funafuti. Selenka describes this species 

 from several centres in the West Atlantic, but I have met with no 

 mention of its occurrence in the Pacific Ocean. 



8. Phtscosoma microdontoton Sluit.' (Plate XXXVII. fig. 7.) 



Several specimens from Funafuti and liotuma- 



Mr. Gardiner's specimens agree well with iSluiter's diagnosis of 

 this species, except in the matter of size. Several of them are 

 over 5 cm. in length, whereas Sluiter gives 1"5 cm. for the length 

 of his Malayan forms ; but as no reproductive oi'gans \Aere observed 

 in his specimens, it is possible that they were immature forms. 

 The gonads are very visible in tlie forms at my disposal at the 

 base of the ventral muscles. In all other respects these specimens 

 agreed with Sluiter's description. 



9. Physcosoma dentigeruji Sel. & de Man. 



Many specimens from Funafuti and Eotuma. 



The species is very characteristic and easy to recognize from its 

 lai-ge papillje confined to the back of the introvert and trunk, and 

 from its coloration. Selenka records it from the Philippines. 



10. AsPiDOsiPHON ELEGANs Cham. & Bysenh. (Plate XXXVII. 

 fig. 8.) 



Seven specimens from Funafuti. Previously described from the 

 Pacific, Philippines, and the Ited Sea. Both this and the next 

 named species were found in tubes bored in the dead coral of the 

 reef. 



11. AspiDosiPHON KLUNZiNGERi Sel. & Biilow. (Plate XXXVII. 

 fig. 9.) 



One specimen from Funafuti. Previously described from 

 Koseir. 



The specimen had been injured and the alimentary canal and 

 brown tubes protruded from a hole in the body-wall, and were 

 broken : consequently it was impossible to see some of the character- 

 istic features of tliis species. The shape of both anterior and 

 posterior shields, the position and structure of the retractors, the 

 number and shape of the longitudinal muscles left, however, little 

 doubt that the specimen belonged to the species A . Uunzingeri Sel. 

 & Biilow. 



12. Ol(eosiphon aspeegillum Quatr. (Plate XXXVII. fig. 10.) 



One specimen from Funafuti. Previously described from numer- 

 ous localities in the Indian and Pacific Oceans. 



The specimen is about 6 cm. in length, apparently a medium 

 size, as those described by Sluiter ° varied from 3-5 cm, to 7-5 cm.
