348 MOLLUSCA. 
Length five-eighths of an inch; breadth half an inch; height one- 
fourth of an inch. 
Inhabits the Sooloo Sea. 
A pretty little shell, most probably a Lotti, resembling some of 
the species figured by Quoy, especially his orbzcularis. Indeed it 
is so like the reticulated variety figured in pl. 71, fig. 33, that the 
examination of a more extensive series might show them to be iden- 
tical. 
Figures 450, 450 a, 450 4, outer, inner, and profile views of the shell. 
Pareua (Lortia?) scapra (Gould). 
Testa parva, scabra, per-inequilateralis, oblique arcuato-conica, palhde 
virens, nigro diversemode virgata, costis radiantibus scabrosis ad 
quindecim ornata; basi ovata: facies interna albida; fundo piceo, 
limbo marginal viridulo et piceo fimbriato. 
Patella (Lottia?) scabra, Goutp; Proceed. Boston Soc. Nat. Hist., 
i. 152. July 1846. Expedition Shells, 10. 
Swett small, rude, the apex near the anterior extremity, rather 
blunt, moderately elevated, and the outline convex, so that the shell 
is more or less dome-shaped. ‘The surface is traversed with about 
fifteen radiating ribs, which are usually irregular in direction, and 
rough. Sometimes there are smaller intervening ribs posteriorly, 
where the ribs are much more developed. Colour greenish, irregularly 
dashed with black, usually between and in the direction of the ribs, 
sometimes inosculating so as to form zigzag markings, and occa- 
sionally, some of the dark spots are dotted with lace-work as in L. 
textihs. Aperture regularly ovate, the edge somewhat scolloped by 
the ribs ; interior bluish-white, with a pitch-coloured spot at the centre, 
and with the margin edged with greenish and black tessellations. 
Length seven-eighths of an inch; breadth five-eighths of an inch ; 
height three-eighths of an inch.
