M. Warrenii, Marrat. A two-banded shell, 20 mill. long. Col- 

 lected by Capt. Warren in the Gulf of St. Lawrence, or — if 

 the latitude and longitude are correctly given — upon the 

 adjacent Canadian territor3^ It is safe to say that no such 

 species lives in that vicinity or within some hundreds of miles 

 of it. 



M. Chemnitzii, Dillwyn. Bleached specimen. 



M. Anna, Jousseaume. Neni Caledonia. 



M. Watsoni, Dall. 



Shell sliort, stout, white or yellowish white, polished, five- 

 w^horled ; suture marked under the glaze with a darker trans- 

 lucent line ; apex obtuse ; in adults the nucleus is obscured by 

 the glaze, in young specimens it presents no differences from 

 the rest of the shell ; last whorl shouldered -roundly, forming a 

 rounded angle at the posterior part of the outer lip ; aperture 

 narrow, labrum and labium nearly parallel ; pillar with four 

 clearly cut folds, the anterior continued around the margin of 

 the canal, slightly flaring, to join the outer lip ; the latter slightly 

 thickened inside, with about a dozen rounded denticulations, 

 outwardly little or not at all reflected, joining the body behind 

 at an acute angle. Long, of shell, 9".5; of last whorl, 8*0; of 

 aperture, 7'5. Lat. of shell, 6'0 ; of aperture, 1'5 mm.

Stream (Pourtales), 447 fms.; Yucatan Strait, G40 fras. 



This species resembles M. vitrea, Hinds, from West Africa, 

 in general shape, but that species is smaller and has the outer 

 lip not denticulated. 31. Watsoni has the facies of a deep-water 

 shell, and does not appear to agree exactly with any I find 

 figured (Dall),
