REPORT ON ZOOLOGY, MDCCCXLIT : 
Pyramidella cincta and glans, Reeve. (Proc. sup. cit. p. 198.) 
Recluz describes, in the Rev. Zool. 184:2, p. 73, some new species of 
Neritce : — N. aurantia, from the Philippines. N. Essingtoni, from New 
Holland. N. (Neritina) cumingiana, from the Philippines and the 
Moluccas. N. ( Neritina ) phasiana, from St. Domingo. N. ( Clithon ) 
rugata, from the Philippines. N. ( Clithon ) sandalina, from the South 
Sea Islands. N. (Clithon) avellana, from Manilla. N. (Neritina) 
serrulata, from Sumatra. 
The same author remarks, ib. p. 177, that the Neritce proper are 
essentially distinguished from the Neritince, by the lateral summit of the 
surface of their columella being incised, and not by the teeth on the 
inside of the labrum. He also describes several additional new species : 
N. corrosula, New Guinea ; Longii, Malabar ; Le Quillouana, Salomon 
Islands ; maura (Chemn. Conch, v. pi. 190, f. 1948-49, atrata, Lam.), 
Polynesia, Madagascar; tenebrosa, Solo Island, North of Borneo; N. 
pisiformis, Otaheite ; N. mittreana, in fresh-water at Grasse in Pro- 
vence ; N. ( Clithon ) souleyetana, Otaheite ; N. ( Clithon ) ohscurata, 
Otaheite ; N. ( Clithon ) spinifera, Island of Guaham ; N. ( Clithon ) 
menheana, Otaheite. 
Some Neritince by Souleyet, which were collected during the voyage of 
the Bonite, are to be found, ib. p. 269. N. indica appears to be N. me- 
lanostoma of the reporter. N. suhlata, from the Philippines, is allied 
to N. subcanaliculata, Recluz. N. touranensis, allied to the preceding : 
Cochin-China. N. vestita, allied to N. duhia ; the epidermis is drawn 
forward over the labrum : Philippines. N. Gaimardii ; green, with 
black undulating longitudinal lines, lip without teeth : Cochin-China. 
Neritina armstrongiana, Hinds’ Annals, x. p. 82 ; black, spotted 
with golden yellow ; spines upon the last whorl ; lip with one blunt 
tooth : Marquesas Islands. 
Recluz describes twenty-one species of Neritce from Cuming’s collec- 
tion, among which are many new. (Proc. Zool. Soc. 1842, p. 168.) 
Neritina tristis, D’Orb., Cuba ; black with white points ; four whorls ; 
columella dentated. N. microstoma, id. ; greenish with narrow black 
undulating longitudinal lines ; perhaps Listeri, Pfr., Archiv. 1840, p. 255. 
Lesson describes (Rev. Zool. 1842, p. 187) a new Neritina (Nerip- 
teron) gigas, which certainly, as Recluz, ib. p. 236, has already asserted, 
is identical with Neritina granosa, Sow. Recluz takes this opportunity 
of dividing the eared Neritce into two divisions : — 1. Neripteron ; t. na- 
vicelliformis, labrum postice superne et inferne productum, interdum 
utrumque canaliculatmn. The species of this section are N. auriculata, 
Lam., tahitensis, Less., ncivicellina, Guillou, hicanaliculata, Reel., 
mbauriculata, Reel., Mauritice, Less. 2. Clypeolum ; t. rotundata 
seu clypeiformis, labrum lateraliter dilatatum seu auctum. Species N. 
latissima, Brod., cariosa, Gray, oiveniana, Gray, rangiana, Mus. Par.,
