Diagnosis

Shell globular, ribs dense on the entire shell.

Type material examined

INDIA • 1 syntype of A. granum ( Fig. 22F–J); Margarita, near Sadia, Assam; Godwin-Austen coll.; NHMUK 1903.7 .1.2511 • 1 syntype of A. multicostulatus ( Fig. 22K–O); Munipur, head of Lanier Rr; Godwin-Austen leg.; NHMUK 1903.7 .1.2557 .

Type localities

“Margarita , foot of Eastern Naga Hills” ( A. granum ); “Head of the Lanier River, Lahupa Naga Hills, N.E. Manipur ” ( A. multicostulatus ).

Remarks

Types of C. granum are much smaller than C. multicostulatus , but there is no difference between those shells other than shell size. Specimens from the Japvo Peak, Naga Hills (labelled as “ A. burrailensis var. minor ”, see also A. burrailensis ) are intermediate in size between C. granum and C. multicostulatus . Therefore, we treat the latter as a junior synonym of the former.
