Saul's Cowrey. Shell oblong-ovate, umbilicated poste- 

 riorly, attenuated anteriorly, sides margiuated at the 

 anterior end, extremities produced, a little reflexed, 

 aperture slightly fiexuous, teeth rather prominent, 

 bold ; back clear cream-colow, painted with a large 

 conspicuous central spot of bright orange chestnut, 

 surrounded wA]\ a few very minute dots of the same 

 coloiur, sides ornamented with a very few dark brown 

 spots, base whitish, teeth whitish, interstices pale 

 golden yeUow.

Hab. Island of Corregidor, Bay of Manila (found among 

 coarse sand and gravel at the depth of seven fathoms) ; 

 Cuming. 



This is one of the most distinct and pleasing species to 

 look upon of any in the genus ; the beautiful economy and 

 deUcacy of the bright sienna painting upon a clear cream- 

 colom-ed gi-oimd, render it an object of peculiar admira- 

 tion.

The red-spotted Cowrey. Shell somewhat cylindri- 

 cally ovate, attenuated anteriorly, sides rounded, ex- 

 tremities a little produced, teeth small, iramerous, 

 elongated partially across the base; back greenish 

 blue, painted with exceedingly minute orange-ches- 



nut dots and a large central mis-shapen blotch of the 

 same colom-, extremities ornamented on each side 

 with a single reddish chesnut spot, sides, teeth and 

 base blueish white.

The Cyprira erythrmjids exliibits without doubt a close 

 approximation to the Cyprmi dolida ; but the ditt'erences, 

 though minute, are constant, and determinable at a glance. 

 In the first place it is uniformly smaller in size ; the spe- 

 cimen here tigiu-ed being rather above the average, and 

 the largest I have seen. In form it vai-ies in being less 

 elevated, more cyKndricaUy lengthened, and attenuated at 

 the anterior end, -mithout that sudden declivity which is so 

 characteristic of its ally. There is moreover a marked 

 variation in the colom'ing : — in all the specimens I have 

 seen, probably some twenty or more, the central dorsal 

 blotch is of a different style, it is more open and irregular, 

 and has no .symmetry of squareness ; I find no indication, 

 either, of the angles of colour which characterize the four 

 corners of the Cypraa stolida, nor are the teeth or edge of 

 the extremities colom-ed.

The cylindrical Cowrey. Shell elongately ovate, some- 

 what cylindi'ical, steep anteriorly, sides with the ex- 

 tremities margiuated, reflexed, base depressly flat, 

 apertm-e anteriorly dilated, outer teeth large, rather 

 distant, inner fine and elongated partially across the 

 base ; back blueish, freckled -vvith very minute fulvous
