PULMONATA OPERCULATA. 
169 
Acicula veneta, proposed by Pirona in 18G6, now established as a distinct 
species by E. de Betta, Malac. Venet. p. 89, Verona and Belliino. The author 
suggests that the figure given by L. Pfeiffer in the new edition of Chemnitz, 
Cyclostomacea, pi. 30. figs. 29-31, for spectobilis (llossm.) represents this 
species. The same is mentioned as Acicula spectahilis (Rossm.) ?, from Pirona, 
Monte Baldo, and Udine, by Betta, Moll. Veron.' pp. 102, 103. 
Truncatella arcasiana, Crosse, figured, J. de Conch, xviii. pi. 7. fig. 13, Fiji 
Islands (cf. Mousson, ibid. p. 196). — T. turricula and funiculus, spp. nn., 
Mousson, ibid. pp. 190, 197, Fiji Islands. 
Assimineah. 
Acinclla, Blanf., elevated to generic rank. Testa ovata, cornea, apertura 
ovata, peristomate obtuso ; operculum corneum, tenuissimum, paucispirale, 
iiucleo excentrico, sinistrali. Animal Assiniinecc simile, proboscide brevi, 
tentaculis brevibus, obtusis, oculos insupcr baud procul ah extremitatibus geren- 
tihus, pode mediocri ovato. A. tcrsa, Bens., lives in moist places, near small 
streams, but not upon their edges, at a height of 4000 feet above the sea, in 
the Khasi Hills. Lingual dentition not yet ascertained. The author admits 
that it may be allied to Assiminca, Blanford, Aim. N. II. (4) vi. pp. 308- 
370. (See Zool. Bee. vi. p. 681.) 
Helicinidas. 
Helicina gallina and mediana, spp. nn., Gassies, J. de Conch, xviii. p. 146, 
New Caledonia . — IL mariei, porphyrostoma, mouensis, and henigna, spp. nn., 
Crosse, ibid. pp. 244-246, New Caledonia. 
Ilclicina tcctiformis, interna, and semperi, spp. nn., Mousson, ibid. pp. 199- 
202, pi. 8. figs. 0-8, Fiji Islands. Some remarks upon varieties of known spe- 
cies from the same islands by Mousson, ibid. pp. 198, 200, 203. 
Helicina mangoensis, sp. n., Sowerby, P. Z. S. 1870, p. 250, Mango Island, 
Fiji. 
Helicina angulata, Sow., and H. hrasiliensis, Gray, both from Rio Janeiro, 
and probably not distinct. Hidalgo, J. de Conch, xviii. p. 69. 
Helicina occulta, Say, found living at Whitefish Bay, Wisconsin, by E. R. 
Lcland ; its dentition photographed by Binney and Bland, Ann. Lyc. N. York, 
ix. pp. 287-290; it differs somewhat from that of H, orhiculata given by 
Troschcl. 
Georissa. The identity of this genus with Hydrocena, Parreyss, in its 
original circumscription, is admitted by Blanford, Ann. N. H. (4) vi. p. 368 
(see Zool. Rec. vi. p. 682). 
Hydrocena brevissinia, sp. n., Mousson, 1. c. p. 194, Vanua-Valabo, Fiji 
Islands. It is not ascertained whether it really belongs to that genus. 
PuGSERPINIDyE. 
Cyane, gen. nov., near Proserpina, base of the columella truncate instead 
of being furnished with a spiral plait ; no palatal parietal laminae. C. hlan- 
diana, sp. n., H. Adams, P. Z. S. 1870, p. 376, pi. 27. f. 2, Eastern Peru.
