“ Ta forme de la machoire des Hyalimaa les distingue de ces divers 
genres ; c’est une combinaison des caractéres de celle des Zonites (pour 
le bord) et des Suceinea (pour le support); le genre Hyalimas est 
done établi trés-légitimement; mais nous sommes certain que 
MM. Adams ne pensaient pas, en le créant, qwil viendrait un jour 
se ranger auprés des Succinea.” 
In July 1872 the same author published another paper on the 
species of this genus (Journ. de Conch. p. 202); and he describes in 
detail Rang’s species Parmacella mauritius, which he places in 
Hyalimax, after showing the points of similarity with HW. maillardi, 
Fischer. The dentition is also of the same type; but I note that the 
dental formula given on p. 205 is 120.1. 120, thus differing very con- 
siderably from that of H. andamanica ; and he concludes by saying :— 
“Le genre Hyalimaw, forme aberrante des Succineide, est le dernier 
degré de l’aplatissement de la coquille des Succinea. Ainsi l’animal 
des vrais Succinea est contenue dans sa coquille; chez les Homa- 
lonyx, la coquille ne recouvre qu’une partie du corps; chez les 
Hyalimax elle devient interne. Les Hyalimaw sont les équivalents, 
dans les iles Africaines, des Homalonyw de Y Amérique.” 
Hyatimax (Jarava) ANDAMANICA, n. sp. (Plate XI. figs. 1, 2, 3, 
and 4.) 
Hab. Near Port Blair, Andaman Islands. 
The animal is thus described by my brother, Mr. Harold Godwin- 
Austen, who sent me four specimens. ‘ Pale watery green, yellower 
on the mantle, with alternate stripes of torquoise-blue and chocolate 
on the upper part of the neck.” ‘These darker lines I suspect are the 
retractor muscles of the eye-tentacles ; the animal when living would 
appear to have a much flattened wide foot, thin, and spreading at 
the margin, for in the spirit-specimen it is much wrinkled ; the extre- 
mity of the foot is pointed, with no mucous gland. There is no defined 
pallial margin to the foot; distinct grooves run at intervals from the 
dorsal edge of the mantle to the side of the foot; and two of the 
specimens show a few distinct dark spots on the upper surface of the 
extremity of the foot. An indistinct median area on the sole of the 
foot. Eye-tentacles apparently stout. I am in doubt regarding the 
oral tentacles ; and if present, they are probably small. The mantle 
is continuous over the shell, and covered with minute papill ; there 
is no division into right and left shell-lobes; the dorsal lobes are 
very much reduced in size, the right dorsal lobe particularly so, being 
very narrow and only extending to the posterior margin; the left 
dorsal lobe is also very narrow, and only just separated from the 
mantle, terminating on the left anterior side. The respiratory 
orifice (fig. 3) is just behind the centre of the right side of the 
mantle, a short distance above its lower edge. The anal orifice,
