30 J. GWYN JEFFREYS ON BROCCHI’S COLLECTION 
P. 351. TrocHus cINGULATUS, 
A broken specimen of 7. zizyphinus, L. 
P. 353. TRocHtUs TURGIDULUS. 
Comprises two species, the smaller of which is 7’. Montacuti, W. 
Wood. 
P. 353. TRocHvs MILIARIs. 
A broken specimen of 7. millegranus, Phil. 
P. 354. TRocuvus cRENULATUS. 
T. exasperatus, Penn. 
P. 354. TRocHUS OBLIQUATUS. 
Not Gmelin’s species of that name, but 7’. turbinatus, Born. 
P. 355, TRocHUS CINERARIUS. 
Not the Linnean species, but a variety of the last. 
P. 358. TrocHvs aGGLUTINANS. 
Several specimens under this name, including Solariwm mediter- 
ranewm of Tiberi. Some of these, especially younger specimens 
and one adult, are umbilicated; this is not a good character to 
distinguish species of Solarwwm, any more than those of Trochus. 
Brocchi’s variety of 7’. agglutinans (p. 360) is a different species. 
P. 359. TRocHUs PSEUDO-PERSPECTIVUS. 
Certainly not (as Brocchi supposed) 7’. hybridus of Gmelin, which 
is a very different species of Solarium or of an allied genus. 
-P. 366. TuRBo EXOLETUS. 
Not the Linnean species, but a variety of Turritella triplicata, 
Bre. 
P. 867. TuRBo DUPLICATUS. 
Same remarks.

The slender variety (gracilis) of Turritella terebra, L. 
P. 376. TuRBo PLICATULUS.
