« These three species, described under the name of Succinea, belong 
to that group of Helicee of which the well-known Hel. gallinasultana, 
Chemn., is the type. The shell having no columella is perfectly 
analogous to that of the genuine Succinee, and we are informed by 
Mr. D’Orbigny’s observations, that the animal of H. gallinasultana is 
also very similar to Succinea in its form and habits. Accordingly 
this species must be related to Succinea, and I believe that the spe- 
cies above described should not be separated from it, although we 
do possess but imperfect notions of their habits. Of one species it 
is noticed that it was found on a species of Juncus, probably in the 
vicinity of water. 
‘« By the same reason (the analogy of shells) I have enumerated 
the Bulimus Broderipii and Coquimbensis among the Succinee (in my 
‘Symbol ad Historiam Heliceorum’).” 
The exhibition was resumed of hitherto undescribed shells con- 
tained in the collection formed by Mr. Cuming in the Philippine 
Islands, and the following descriptions of them, by Dr. J. H. Jonas, 
were communicated to the Meeting. 
Hewrx Zeus. Hel. testd perforatd, orbiculatd, subdepresso-convexd, 
rugis obliquis striisque spiralibus elevatis sculptd ; anfractibus 44 
conveais ; ultimo medio angulato, supra carinam depresso, infraque 
inflato ; colore brunneo, lineis flavis ziczacformibus obliquis superne 
pictd, inferne rubra, fascid latd fuscd infra carinam ornatd ; aper- 
turd subtrapeziformi, fauce albd, peritremate acuto, recto, supra 
umbilicum reflexo. 
Hab. ad insulam Mindoro, Philippinarum. 
Altitudo, 1 poll ; latit. 23 poll. 
This species bears a great resemblance to Hel. Otahaitana. ‘The 
rugulosities on the upper part are more elevated, as on the under 
side, where the regular concentric lines are more distinctly visible. 
Buxiimus catopartus. Bul. testd umbilicatd, ovato-pyramidali, 
tenui, subdiaphand, nitidd, rubra vel pallidd, fasciis flavis undu- 
losis longitudinaliter pictd, striis incrementi subtilissimis spirali- 
busque oculo nudo vix conspicuis decussatd ; anfractibus 54 convezis, 
suturis appressis, ultimo dimidiam teste partem fere equante ; 
apertura ovali, intis albd, marginibus reflexis, albis, sinistro umbi- 
licum partim occultante. 
Longit. 14 poll. ; latitudo, 2 poll. 
Hab. ad insulam Mindoro, Philippinarum. 
In form this beautiful shell resembles Bul. Myersii, Miiller. 
Var. a. Ground-colour brownish red and shining ; the longitudinal 
zigzageed stripes are of a golden yellow colour, and on the last vo- 
lution they are interrupted by a brown transverse line. 
Var. 6. Ground-colour pale yellow; the longitudinal stripes as in 
Var. a. No transverse line on the last volution. 
BuLimus BALANOIDES. Bul. testd imperforatd, ovatd, albd, epider- 
mide flavd, vittis spadiceo-rufis cinctd ; anfractibus senis convexius-
