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.
