On the Breeding-habits of Chromis philander. 321 
An ally of B. meridionalis, Pfr., but differing in both 
coloration, texture, and form. 
Melampus ordinarius, sp. n. (PI. II. fig. 14.) 
M. testa solida, gilvo-straminea, conico-pyramidata; anfractibus 
novem, quorum apicali mamillato, in sp. juvenili acuminato, 
septem superioribus compressis, angustissimis, ultimo permagno, 
ad peripheriam subangulato, levi, obeso; apertura oblonga, apud 
basin latiore ; peristomate parum incrassato, intus spiraliter et 
superficialiter quatuor-plicato; columella biplicata. 
Long. 10, lat. 4°50 mm. 
Hab. Mouth of Umlaas River, Natal (Burnup). 
This small and somewhat insignificant Melampus was 
found in company with M. castaneus, Muhlf., and Assiminea 
umlaasiana, Smith, in a cavern at the habitat given above, and 
though its characters are not prominent, we are unable to 
assign it to any known species. We have examined several 
examples in various stages of growth, the apex being very 
acuminate in young specimens.

XLII.—On the Breeding-habits of Chromis philander. 
By NENDICK ABRAHAM. 
THE fact that African Chromids take care of their ova and of 
the young for some time after hatching has been ascertained 
by several observers—first by Lortet* on CA. simonis from 
the Lake of Galilee, then by Max Weber f on Ch. philander, 
* Compt. Rend. v. 1875, p. 1196.
