ALCITHOE. 95 



Only a single specimen known. F. Cleryana, Petit (fig. 101), 

 is the young of it. 



Y. FESTIVA, Lam. PL 30, fig. 125. 



Rosy white, clouded with orange-red, with chestnut spots and 

 bands formed of series of longitudinal flexuous chestnut striga- 

 tions. There are three prominent oblique plaits at the lower 

 part of the columella, and above them a number of oblique 



rugosities. Length, 4-5 inches. 



East Africa. 



One of the rarest of Yolutes. The exact locality is unknown. 

 D'Orbigny speaks of collecting it on the Patagonian coast, but 

 he doubtless refers to F. Magellanica. 



Y. AFRICANA, Reeve. PI. 30, fig. 127. 



Orange-brown, with sparse hieroglyphic brown markings 

 disposed in bands ; upper part of columella black. 



Length, 2*5 inches. 



E. Africa. 



The type, which formed part of the Curning collection, is not 

 in good condition, so that the pattern of painting is obscure. 

 It is closely related to V. f estiva, but appears to differ in its 

 greater proportional width and short spire. 



Y. MEGASPIRA, Sowb. PL 28, fig. 102; PL 30, fig. 132. 



Reddish flesh-color, longitudinally marked with zigzag 

 chestnut streaks, sometimes forming three obscure bands. 



Length, 4 inches. 



Japan. 



An elegant smooth species ; rather thin, with the first volution 

 of the papillary apex lateral instead of terminal a character 

 shared by some of the following species. The animal is a 

 common article of food in Japan, yet the shell is rather rare in 

 collections. F. lyriformis, Kiener (not Swains.), is apparently 

 a variety of this species, although Mr. Crosse has recently 

 characterized it under the name of F. Prevostiana (fig. 132). 



Y. FUSIFORMIS, Swainson. PL 28, fig. 103. 



Fulvous or flesh-colored, with irregular, zigzag, longitudinal 

 chestnut markings. Length, 6-7 inches. 



Tasmania; So. Australia.
