SAKIELLA. HOLKEION. 239 



[From Stoliczka's description (J. A. S. B. 1871, p. 249): 



" The animal of the Moulinein variety is narrow, very long, pale 

 white, pedicles and the termination of the tentacles leaden grey, 

 as well as the upper part of the foot posteriorly ; the tail-gland is 

 superseded by a very distinct hook ; the mantle-lobes are well deve- 

 loped, both the upper portions being reflected over the shell. By 

 some accident, however, my spirit-specimens were lost and I am, 

 therefore, unable at present to give sufficient details regarding the 

 anatomy of this species." 



The descriptions which follow at the bottom of pp. 249 & 250 

 refer to the animal, anatomy, spermatophore, jaw, and radula of 

 a species from Burma collected by Dr. Anderson, evidently Macro- 

 chlamys honesta, var. andersoniana, Nev., which is a "distinct 

 species (vide suprci, p. 141, no. 192). 



The animal (three species observed) from Mule-it Mountain near 

 Moulmein is pale-coloured, a dark line on the upper side of the 

 foot, with three or four conspicuous black spots on the side above 

 the peripodial grooves ; these spots when extended in life would 

 appear as dark streaks. The right shell-lobe is long, narrow, and 

 pointed, and there is a small tongue-like left shell-lobe. The 

 visceral sac is spotted, the spots arranged in four parallel rows* 

 The genitalia were not well seen, but the amatorial organ was 

 present and the spermatheca was not very long. The jaw is 

 moderately arched, with no median projection. The radula is 

 remarkable for the very large number of teeth in the row. The 

 centre tooth is on an elongate narrow plate, tricuspid ; the first 

 admedians on similar plates, with a single small cusp much below 

 the points ; the laterals are all alike, becoming smaller towards 

 the margin and unevenly bicuspid ; the formula being 153 . 1 . 153, 

 or 307 in the row. The jaw and radula are quite distinct from 

 Stoliczka's figures on plate 17, figs. 10 & 14, J. A. S. B., and 

 Semper's pi. 5, fig. 20, Eeis. Phil. 1870.]

These shells are in the Indian Museum, Calcutta, and I have 

 not been able to see them.] 



[Genus HOLKEION. 



Type, H. anceps, Gould. 



Range. Upper Burma, Moulmein, Mergui, and Northern Siam. 



Stoliczka places anceps in the genus liotula, not considering 

 it sufficiently like Macrochlamys to leave it in that genus. The 

 shell differs very much in character, being sharply carinated at 

 the periphery; the whorls numerous, narrow, flattened, and
