lines. Inhabits North Carolina. Resembles C. marginatus and more 
nearly still C. cristatus from Oregon. 
Cycurus Leonarpu. Black ; head transversely striated ; thorax viola- 
ceous, subquadrate, narrowed behind ; elytra broad ovate, carinated at the 
sides, bronzed violet, deeply crenato-striated. Length, including mandi- 
bles, from 11 to 13 lines. Inhabits northern and western parts of Massa- 
chusetts and New Hampshire. Hitherto confounded with C. viduus, from 
which it essentially differs in color and its more dilated form. 
Cycurus Tusercucatus. Black opaque; bead rugose and with two 
longitudina] impressions on the front; thorax rugose, truncato-cordate, 
contracted behind; coleoptra ovate, very convex, granulated, with a triple 
series of smooth tubercles on each elytron; epipleura rugosely punctured. 
Length 7 to 8! lines. Inhabits Oregon. 
Cyrcurus ancutatus. Black; head carinated; thorax angulated at 
the sides, much contracted behind; elytra violaceous-brown, somewhat 
flattened, crenulato-striate ; legs brownish-piceous. Length 6 lines. 
Inhabits Oregon. 
Cycurus cristarus. Black; head carinated; thorax cordate, con- 
tracted behind; elytra crenato-striate, with a narrow, blue margin. 
Length 5: lines. Inhabits Oregon. 
Dr. Harris exhibited specimens of Nymphea odorata (var. sanguinea) 
from the Botanic Garden, Cambridge; and remarked upon the tendency, 
strongly exhibited in these specimens, which all the parts of the flower 
have, to become leaves. | 
r. Goutp remarked that this lily was originally brought from Mossy 
Pond, in Lancaster, where it grows in one small spot. He was inclined to 
_ regard it as a distinct species, having constantly fonnd the angles of the 
leaves more prolonged, the color darker and the size smaller than in N.

Mr. C. B. Anams, had spent a day at Fresh Pond, and gave an account 
of the shells he had found there. They were the following species, V2. : 
Unio nasutus, complanatus, and radiatus; Anodonta implicata, Say; 
Cyclas similis; Planorbis trivolvis, bicarinatus, deflectus? and hirsutus, 
MS.; Valvata tricarinata; Succinca ovalis; Lymnea heterostropha, col- 
umellaris, catascopium, Physa heterostropha, Paludina decisa, hus rica? 
Of Unio nasutus only one specimen was found, U. radiatus was abun- 
dant, clean and beautiful. From one of them dropped a beautiful pearl 
in the form of a flattened sphere, .16 inch in the longer and .11 inch in 
the shorter diameter. Of Anodonta implicata, Say, he said, that a com- 
parison of adult shells only, with specimens of A. cataracta from other 
calities might lead to the conclusion that they were distinct species ; but 
an examination of them in every stage of growth from the size of the
