There are also specimens of this species in the United States 

 National Museum collected at Porta Galera Bay, Mindoro, by S. F. 

 Light, and at Bantayan by Dr. L. E. Griffin and Mr. L. D. Wharton. 

 The latter, though of the usual brown shades in preservation, are 

 recorded as " soft green " in color when fresh. Perhaps this is the 

 usual color of fresh specimens. 



Gottschaldt (1898) described this species from numerous speci- 

 mens taken at Ternate. 



Genus POLYSYNCRATON Nott, 1892. 



As already noted by Sluiter (1909), the propriety of including the 

 following species in this genus seems doubtful, as it has the atrial 

 aperture produced into a tube and lacks an atrial languet. In Nott's 

 (1893) original species the atrial aperture is not produced, and a 

 languet is present. In common with Nott's species, however, it has 

 the testis cleft into a number of entirely distinct glands, a spirally 

 coiled sperm duct, and four rows of stigmata.
