described by Hoyle (1904) from Arno Atoll, Marshall Islands. In 

 view of this I have consigned the present specimens to Grant's species. 

 However, since Adam (1954) fomid species referable to morsei and 

 herryi to the southward in Indonesia, these latter two species almost 

 certainly wUl also be found to occur in the Philippines. The 18 

 specimens available to me are remarkably consistent in their characters 

 and show little variation. If we accept the arrangement of the sessile 

 suckers of the male as diagnostic, they may be easily distinguished 

 from all other species. 



Distribution. — Mauritius (Grant). Kangiroa, Tuamotus; Funa- 

 futi, Ellice Islands; Tarawa, Gilbert Islands, Arno Atoll, Marshall 

 Islands (all Hoyle). Bikini Atoll, Marshall Islands (Voss). Philip- 

 pine Islands!

Material. — ^1 cf , ML 15.5 mm., from Cebu market. Mar. 20, 1909; 

 USNM 575333. 1 cT, ML 14.0 mm., 1 9, ML 12.5 mm., Sta. D5159, 

 off Tinakta Id., coral sand, 18 m., Feb. 21, 1908; USNM 575334. 



The three specunens listed above appear to belong to this well- 

 known species, but they are in a poor state of preservation, with most 

 of their suckers absent, and are badly distorted. However, from the 

 size of the sucker bases on the ventral rows of all the arms and the 

 occassional greatly enlarged suckers still present on the ventral rows, 

 they have been tentatively placed in this species. 



Type.— Yale University. 



Type locality. — ^Yeddo Bay, Japan. 



Distribution. — Japan (numerous records by Sasaki); Indonesia, 

 Makassar, Amboina (all Adam) ; Philippine Islands!
