234 BET. E. B. WATSON ON THE 



Tarn. SCAPHANDBID^. 

 Gen. Cxlichna, Lov. 

 1.* Ctlichna speeta, n. sp. 



Shell smallish, oval, somewhat broad just below the middle 

 and contracted upwards, truncated above, where the edge is 

 carinated and thickened but not furrowed. Longitudinals : the 

 lines of growth are very faint, delicate, close-set, and hair-like. 

 Spirals : there are very slight and superficial microscopic scratches 

 which extend to the whole surface. Colour dull pellucid white. 

 Month club-shaped, bent, narrow above, widened but drawn out 

 and lop-sided in front. Outer lip rising from the outer edge 

 of the apex, bends back, and with a slightly patulous front 

 makes a miuute semicircular sweep round the top, whence with 

 a slight divergence in its direction to the right it ruus straight 

 forward, with a barely retreating edge, till it nears the point of 

 the shell, where scarcely patulous it sweeps round and merges 

 with a very faint twist into the point of the pillar, continued up 

 the bod} r as a mere film to its junction with the outer lip. Apex, 

 which is contracted and small, consists of the round edge which 

 is thickened by a pad within the shell, in the centre is a somewhat 

 abrupt minute pore. — L. 0*09 in. B. 005. 



This species a good deal resembles the young shell of C. ovata, 

 Jeffr., but has the mouth more bent, the swell of the body- 

 whorl lies higher and is not so large, while the apex and the 

 front of the shell are smaller; the apical pore is also more 

 contracted. 



The few specimens of this species I got from about 30 to 

 40 fms. off Porto JSanto ; they are nearly all quite young shells. 



Gen. Amphisphtba, Lov. 



2. Amphisphtba flata, n. sp. 



Shell globose, thin, glossy, brownish yellow, with large open 

 mouth and a hidden spire. Sculpture : there are faint soft longi- 

 tudinal undulations, and, like these, following the lines of growth 

 are very fine silky striatious with a mere suggestion of spirals 

 in the structure of the shell. Colour yellowish with a faint 

 tinge of ruddyish brown. Spire very small, and sunk in a 

 minute pore-like depression. Whorls : that of the body, which 

 is alone visible, is shortly globose above, but, below this, on the 

 left is hard twisted in round the pillar, while, in forming the
