Fam. Littorinidae. 
Littorina cincta Quoy & Gaimard. 
North Island: 3, some small sps. — Stewart Island: 36, 4 sps., 
h. 11.5. — Auckland Island: 37, many sps., h. 18. 
Littorina infans E. A. Smith. 
North Island: Cape Maria v. Diemen, shaken from algae, some 
small sps., max. h. 1.3 mm, whorls 4. 
Compared with specimens of this species from Sydney, sent 
by the Australiari Museum, the samples at hånd prove to be iden- 
tical, as they have the same dark-brown colour with the yellow basal 
band appearing most clearly within the aperture. The specimens 
are not- full-grown, and may be taken for juvenile stages of L. 
cincta, but they have a smoother incremental sculpture. The species 
is now for the first time recorded from N. Zealand. 
Littorina mauritiana (L a m a rc k). 
North Island: 3, some small sps. — 9, 2 small sps. — Ild, 
some small sps. — 19, numerous small sps., h. 11, high above 
the water, or in pools beneath plants. — Island Bay, Wellington, 
the coast, 22/1 1915, 4 small sps. 
Laevilitorina antipodum (Filhol). 
Campbell Island, 44, numerous sps., h. 5. 
Fam. Fossaridae. 
Fossarus ovatus n. sp. 
(PI. II, fig. 58.) 
Shell small, fragile, elongate-ovate, hyaline white, shining, rimate. 
Whorls 4 1/2, separated by a deep suture. Protoconch (the first 2 
whorls) smooth; apex somewhat obliquely flattened; the subsequent 
whorls convex. Spire as high as aperture, with convex outline; 
base slightly convex. Sculpture: very fine spiral striae at regular 
intervals, the two uppermost striae below the suture broader; be- 
sides fine lines of growth, a little flexuous, here and there somewhat 
elevated to fine longitudinal ribiets causing an indistinct reticulation.
