A comparison of the types of the above-named species shows that they are merely different 
stages of growth of one and the same form, 
49. Terebra (Myurella) violascens, Hinds, var. 20,), 37, X//. II, IV, VI. 
The specimens from the above stations are not typical and vary inter se. None are of a violet 
tint, but whitish or yellowish. The shell described by Reeve had the whorls undivided by a groove 
or punctured depression, whereas Hinds described the type with whorls ‘“superné lined impressa 
obsolete cinctis.” The Maldive specimens agree with the type in this respect. Terebra exigua, 
Deshayes, and 7’. polygyrata, Deshayes, are probably only slight varieties. 
50. Terebra (Hastula) lanceata, Linn. 37, X/Z. (var. penicillata, Hinds, 37, XJ/J, var. 
venosa, Hinds, 37, XZ/.). XV. 
The specimen from Minikoi (station XV.) belongs to the variety penicillata.
