GARRETT: ON POLYNESIAN MITRID^. 33 



The animal is deep chocolate-brown. The creeping 

 disk the tentacles and siphon pure white. 



74. Strigatella brunnea Pease. Amer. Jour. Conch., 1867, 

 p. 215, pi., XV., fig. 7. 



Excepting the Marquesas, Tonga and Viti Islands, this 

 rare species occurs at all the other groups, and like the 

 preceding lives under dead coral on the outer reefs. 



Perfect fresh shells are dark ashy-brown, olive-brown or 

 chestnut-brown with a bluish-white aperture, and the edge of 

 the outer lip is dotted with light brown. 



Animal milk-white. 



75. Strigatella columbellseformis Kiener. Reeve, Conch. 



Icon., pi. xviii., fig. 138. 



This fine large Strigatdla which is somewhat rare, occurs 

 beneath large coral blocks on the outer reefs, and was 

 obtained at the Kingsmill, Society, Cook's and Paimotu 

 Islands. In the 'Catalogue Museum Godeffroy' it is recorded 

 from Samoa group. Reeve and other authors cite Mada- 

 gascar as its habitat. 



Our shells vary from uniform dark brown to olive-brown, 

 more or less varied with white under a thin olive-yellow 

 epidermis. The transverse impressed lines mentioned by 

 Reeve are minutely punctured. 



The animal is rich chestnut-brown with a diluted-white 

 creeping disk. Head slightly varied with white. 



76. Strigatella litterata Lamarck. Reeve, 1. c, pi. xx., fig. 153. 



More or less plentiful in all parts of Polynesia except 

 the Marquesas, where we failed to obtain examples. They 

 are found lurking under dead coral in holes and crevices on 

 the outer reefs. 



They are subject to considerable variation in size and 

 character of the markings. Reeve's figure is very accurate.
