Very rare where I made collection, but common in other places. 
Operculum lamellar, horny. 
Palate, 1.1.1. Lateral has no basal tooth. Median, three 
denticles, middle one longest. Specimen in cabinet of R. M. S. 
Purpura (?), No. 24. — Small whelk, purple inside. Hab., near 
low water on serpuhe-covered rocks. Common. Operculum claw- 
shaped, horny. 
Palate, 1.1.1, very like that of Nassa, but much smaller. The 
denticles of the laterals are long and thin. Specimen in cabinet of 
E. M. S. 
Purpura (?), No. 39. — Brown whelk, similar in shape to the 
last, but the mouth was thin and semitransparent. Shell covered 
with a dark brown epidermis, which was produced into irregular 
longitudinal short fringes. The palate is different from Buccineadse. 
I have no specimen of shell. The only one I met with was 
transmitted to the late Mr. Hall ; it may probably belong to 
Muricidse. 
Palate, 3.1.3. Median reflexed, denticulated. 1st and 2nd 
laterals slightly denticulated. 3rd smooth. 
Purpura (?), No. 45. — Shell transversely ribbed ; inner lip 
callous, extends over large portion of whorl ; outer lip thickened. 
Possibly Nassa tliersites. Hab., low water. Specimens were found 
in enclosure for graving dock. 
Palate, 1.1.1. Central tooth lunate, with numerous round 
pointed denticulations. Lateral teeth with a basal tooth and small 
flat processes on inner side. 
Conid^. Conus, No. 40 (C. punctatus ?). — Shell with thick 
dark-brown epidermis. Marked with irregular brown spots. 
Column plicated at lower portion. Animal pink, with black eyes. 
Hab., near low water. Only found on two occasions. First a 
single specimen, from which I failed to obtain the palate. Second, 
when there was an extra low tide and calm weather, when I obtained 
several. 
Palate, 1.1. Teeth long, serrated near tips. Bases orbicular, 
very difficult of dissection. 
Naticidje. Natica , No. 46. — Hab., sand near cockle bed 
between tide marks. Very rare. Operculum large, paucispiral, 
horny ; jaws spiny ; very large mouth ; short foot. 
Palate, 3.1.3. Median reflexed ; three denticulations. 1st and 
2nd laterals, claw-shaped, bifid. 3rd lateral simple. 
Note. — On drawing this shell in my diary I find there is another 
(probably a Naticina) that I had erroneously considered but a 
variety of this. 
Natica (?), No 26. — Small striped marine snail. Abundant.
