260 DOLTID.E. 



" In another species which I observed, and of which I also 

 made a drawing (the Ficula Isevigata, Reeve), the mantle is 

 bright pink, mottled with white and deeper pink, the under 

 surface of the ventral disc being of a dark-chocolate color, with 

 yellow, scattered spots ; the head and neck are pink, and also 

 colored with 3 T ellow spots. 



"The Ficula shells, seen in cabinets, convey but a poor idea of 

 these handsome mollusks, observed in the living state, crawling 

 rapidly along, bearing their light, elegantly formed shells, easily 

 and gracefully, with their siphons erect, their foot expanded, like 

 a broad flattened disc, and their bodies ornamented with delicate 

 colors, beautifully marbled, and moving their long, flat heads, 

 and peering about with their large, black eyes, in a manner 

 which is surprising, when one considers the position these 

 animals occupy in the scale of creation, arid that but a very 

 small share of intelligence is, in general, supposed to be the lot 

 of most mollusca." Narrat. Voy. Samarang, ii, 358. 



Subgenus PTYCHOSYCA, Gabb, 1876. 



Shell shaped like Pyrula ; inner lip with one anterior very 

 oblique fold. 



P. inornata, Gabb. Cretaceous, Georgia (Fig'd S. & S. Conch., 

 t. 62, f. 39). 



Dr. Fischer thinks it allied to Liostoma. 



Subgenus FICULOPSIS, Stoliczka, 1867. 



Pyriform, attenuated in front, inflated behind ; spire very 

 short ; surface spirally and transversely striate or costulate ; 

 columella thick, angulated, plicate. 



P. Pondicherriensis, Forbes, Cretaceous, So. India (Fig'd S. 

 & S. Conch., t. 62, f. 38). 



The family has been monographed by Reeve, Kiener and 

 Kiister (Conchylien Cabinet). Kobelt has also published a 

 catalogue of the species of Dolium in Jahrb. Mai. Gesell., ii, 263, 

 and Hanley another, in Proc. Zool. Soc. London, 491, 1859. 

 Sowerby monographed Ficula in the Thesaurus, iv, 1880, and 

 Kobelt catalogued it in the Jahrbiicher, 359, 1875, and published 

 a monograph in Kiister's Conch. Cab., 1874.
