182 CONIDEA. 



inch in length, appears to be a connecting form with (7. pardalina, 

 var. sagena. Voluta tringa of Linnaeus and of Lamarck's first 

 edition is a difficult species to make out; it has been referred, 

 with some justice," to Mitra. In the second edition of Lam., 

 Deshayes repeats the original description, including the three- 

 plicate columella, but decides that the shell is a Columbella. I do 

 not think he had good grounds for this decision, but as the shell 

 I herein figure has become known to conchologists under this 

 specific name and authority it appears more convenient to con- 

 tinue to use them. C. undata, Duclos (fig. 66), is a synonym. 



C. FLAVA, Brug. PI. 59, figs. 67-72. 



Shell cylindrically oblong, smooth, with revolving striae towards 

 the base, covered by a thin epidermis ; orange-brown to choco- 

 late, spotted and blotched with white, interior of aperture 

 usually more or less violaceous. Length, '75-1 '1 inches. 



Indian Ocean, Japan, Mauritius, New Caledonia, Polynesia. 



I figure two well-marked types of coloring in this species ; it 

 is ver}' variable, approaching C. tringa on the one side and G. 

 discors on the other, and it is not unlikely that these, as well as 

 several other allied species, will eventually be consolidated. G. 

 punctata, Sowb. (fig. 69), C. lugubris, Kiener (fig. 70), C. funi- 

 culata, Souv. (fig. 71 \ are synonyms. G. rubicundula, Quoy 

 (fig. 72), may possibly belong here ; it is unknown to me except 

 through the description and (apparently) poor figure. 



C. DISCORS, Gmelin. PI. 59, figs. 73-77. 



Shell obovate, with short, conically convex spire; chestnut- 

 colored or orange-red, spotted or interruptedly strigate with 

 white, with frequently a few larger white spots and a broad 

 orange sutural band ; interior of aperture often violaceous. 



Length, '75-1 inch. 



East Africa, Borneo, Japan, Philippines, New Guinea. 



The synonyms are C. semipunctata, Lam. (fig. 74), C. splendi- 

 dula, Sowb. (fig. 75), G. zelina, Duclos, (fig. 77). 



C. EUSTOMA, Jousseaume. PI. 59, fig. 78. 



Shell oblong, obesely acuminate, smooth, shining, white macu- 

 lated with chestnut ; aperture violet-tinted. Length, 15 mill. 



Habitat unknown. 



The figure appears to represent a shell of abnormal growth.
