Brot, Conch.»Cab. I, pl. 13, fig. 11, as M. spinosa, var. B.

Excellently represented by the above quoted figure. As M. Brot 
justly remarks if c. page 93], it is an interesting and important 
transitional form between typical M. variabilis and M. episcopalis. 
var. pseudospinosa. 
Nevill, J. A. 8. B. 1881, pl. VI, fig. 17, Assam ; Con. Indica, pl. 75, fig. 6. 
I can detect no good character to distinguish this form 
from Perak and Malacca specimens; the spire is usually more 
produced and less decollate, the ribs more spinose at the angle, 
which, again, is more central.

Fairly intermediate between M. Brot’s pl. X, fig. 2B [“ M. 
swmatrensis”] and his pl. 12, fig. 2 [“M. spinosa”]; upper 
whorls longitudinally ribbed. 
Long. 68, diam, 24 mil. ; 9 whorls. 
6 Tezpore; coll. Dr. F. Stoliczka. 
One or two of these are scarcely separable from my Perak 
typical episcopalis. It is possible they had better been’ ciassed 
in subvar. pontificalis ; the sculpture of the upper whorls in all 
of them is very superficial. 
2 Assam; exc. Dr. F. Stoliczka. 
Not quite adult; may be the young of M. Brot’s pl. 10, 
fig. 1A |‘ M. variabilis”], perhaps better classed as var. sub. 
typica, subvar. subinfracostata.

Esq., and Capt. Butler. gL ]3 co! Peal 
Agree fairly with Con. Indica, pl. 75, fig. 6 [ MM. spinosa all 
one specimen (undoubtedly of the same stock) is very interest- 
ing, as the last whorl is smooth.
