Var. decipiens. 
Triton decipiens, Reeve, fig. 102; Tryon, pl. xvii. fig. 178; Kobelt, 
pl. xvii. fig. 7. 
Hab. Philippines (Reeve); lat. 21° 30’ 15” N., long. 
68° 05! 45” E., Arabian Sea, off Gujerat, in 82 fathoms 
(‘ Investigator ’). 
The specimens obtained by the ‘ Investigator’ more closely 
resemble the last variety than any other. The colour of the 
outer lip and the columellar callus is the same. The form of 
the aperture is quite similar, but there is only a single parietal 
tubercle instead of three or four, as usual in this variety. 
They are clothed with a hairy epidermis, the hairs being 
placed in longitudinal rows upon the ridges. In the inter- 
stices the epidermis is minutely reticulated and setose, and 
the general appearance is fibrous. The embryonic shell 
consists of three smooth, convex, glossy whorls, and the 
normal volutions have a more regular convex and less dis- 
torted aspect than in Reeve’s type. 
Triton constrictus of Reeve is considered synonymous with 
this species by Tryon, who remarks that it, together with 
T. ridens and T. decipiens, “ have no claim to rank even as 
varieties.” Although in general conformation 7’. constrictus 
resembles the other forms mentioned, I consider that its great 
solidity, the much more distorted spire, coarser sculpture, and 
heavy labrum are sufficient to separate it specifically. The 
geographical range also is quite different. With regard to 
the generic name to be applied to this group of “ Tritons,” 
there appears to be some divergence of opinion. Casting 
aside the uncharacterized Boltenian catalogue-name of Dzs- 
torsio, the most available appears to be Distortrix of Link 
(1805). 
Capulus trregularis. 
Testa pileiformis, apice postice valde recurvato, sordide albida, 
pallido-rufo radiatim obscure picta, lamellis irregularibus concen- 
tricis undulatis instructa; anfractus 3, apicales duo (nucleus) 
globosi, leves; forma aperture irregularis, vel rotundata, vel 
elongata, etc.; superficies interna albida, plus minus rufo tincta, 
nitida ; peristoma antice tenue, postice intus incrassatum. 
Diam. maj. 153 millim., min. 12; alt. 8. 
Hab. Lat. 20° 37’ 15” N., long. 69° 24’ 20” E., Arabian 
Sea, off Gujerat, in 44 fathoms. 
Like Capulus lissus, Smith, this species has no radiating
