REPORT ON THE MYZOSTOMIDA. 



37. Myzostoma clentatvm, Graff. 



A specimen measuring 27 mm. in length, lying loose in a vessel along witli Actino- 

 metra Solaris, Actinometra bennetti, and five species of Antedon, from the Molluccas 

 (K. zool. Genootschap, Amsterdam). 



38. Myzostoma jimhriatum, Graff. 



Two specimens found on Antedon quadrata, P. H. C, from Station 48, Challenger 

 Expedition. Both were almost circidar, the one measuring 2 mm., the other 2*3 mm. 

 in diameter. The cirri of the latter measured 0'17 mm. in length, so that the length 

 given in the Report (p. 49) must have referred to much contracted cirri {cf. also the 

 figure). The habitat of the above specimens has removed any doubt as to whether the 

 host was Antedon eschrichtii or Antedon quadrata.
