From Sykes 1925
81. Homalogyra sinuosa, n.sp. (PI. IX, Fig. 8.)
Shell depressed, slightly concave above and more so below, thin, white; whorls 3-4, with deep suture, the last rapidly increasing; sculpture, well-marked sinuous riblets (under a lens) which gradually become weaker towards the mouth; mouth rounded with the outer margin projecting forward, lip thin. Diam. max. 1-2 mm.
" Porcupine " Expedition, 1870, Station 17.
St.17 = N39°42’/E09°43’ (Atlantic)
Two specimens. Related to //. densicostala, Jeffr., but the riblets are more sinuous and more widely spaced; also the present species lacks any spiral keel.
