550 REPORT—1863. 
160. Cancellaria pygmea= C. goniostoma, jun., no. 157, =M. 446. 
164, Pleurotoma atrior = Drillia vy. Melchersi, M. 461. 
169. Pleurotoma discors, C. B. Ad., is probably a finely developed var. of D. 
aterrima. 
182. Plewrotoma rustica, C. B. Ad.,=worn specimens of D. Melchersi, no. 164. 
191. Mangelia neglecta, probably =M. acuticostata, M. 473. 
194, 195, 201 belong to Cerithiopsis. 
196. Cerithium famelicum must stand for the West Coast Uncinoids, M. 383; the 
Cumingian shell, and two out of ten in the type-series, belong to C. me- 
dioleve, M. 582. : 
198, 199, 200 are various forms of C. stercus muscarum, Val.; quite distinct from 
C. interruptum, Mke., and C. irroratum, Gld. 
203. Does not correspond with the diagnosis, and must stand as Chrysallida pau- 
percula, a very distinct species. 
208, Is scarcely a variety of Zriforts alternatus, no. 207. 
209. Both the specimens are dextral, = Cerithiopsis tuberculoides, M. 557. 
210. Turritella Banksii, C. B. Ad. (non Rve.)= 7. goniostoma, jun., M. 379. 
217. A dead, stunted specimen of Caecum undatum, M. 871. 
220. Chemnitzia acuminata is a very broad but typical species; not Chrysallida. 
221. Chemnitzia affinis, Mus. Cum. and M. 523, has sufficient correspondence with 
the diagnosis; but the type= Ch. undata, M. 531. 
222. Chemnitzia clathratula. The type-series contains Chrysallida clathratula, 
M. 513 and Mus. Cum.,+ Chr. communis+ Chr. effusa, M. 510,+ Dunkeria 
subangulata, M. 537. 
223. Chemnitzia communis, the type of Chrysallida, M. 507, Cpr. (vix A. Ad.). 
The type-series also contains Chr. effusa+ Chr. telescopium, M. 508,+-Dun- 
keria subangulata, +?do. var. 
225. Chemnitzia major ranks with Dunkeria. 
227. Chemnitzia Panamensis contains also Ch. Adamsii, M. 519,+ Ch. ? gracillima, 
M. 530. 
228. Chemnitzia similis, like aculeus ; differs from Ch. Psimilis, M. 520, which per- 
haps= Panamensis, vax. 
930. Chemnitzia turrita=251, “ Rissoa, sp. ind.” 
231, 235, 237, 238. These species of “ ? Litorina” belong to Fossarus. 
233. Litorina atrata+ (adult) 257, P-Adeorbis abjecta, are the same (variable) species 
of Fossarina, A. Ad. . 
239. Litorina parvula, C. B. Ad. (non Phil.),=L. Philippi, M. 598. 
244. Rissoa firmata+ (jun.) 250, R. scaliformis= Rissoina, sp. M. 409. 
246, ? Rissoa inconspicua, C. B, Ad. (non Ald.), does not accord with the diagnosis, 
but is identical with Alvania tumida, M. 414. 
249, Rissoa notabilis+ Cingula ?turrita belongs (with 252 and 254) to another 
suborder, = Parthenia quinquecincta, M, 498. ‘ 
252. ? Cingula inconspicua= Chrysallida ovulum, M. 512. 
253. Cingula paupercula=? Odostomia mamillata, M. 492,= Diala. 
254, Cingula terebellum=Parthenia exarata, M. 501. 
261. Vitrinella minuta. The original type accords better with Lthalia. 
266. Vitrinella regularis is also an Ethaha. 
269. Vitrinella valvatoides. Probably an Zthalia. 
270, 271. Are apparently vars. of Solariwm granulatum. 
272. May be disangwisped as Torinia rotundata, from its great superficial resem- 
blance to Helix rotundata. 
275. Trochus Leanus is a pale var. of Calliostoma M* Andree. 
276. Trochus lima can scarcely be distinguished from C. Antonii, Mus. Cum., 
dredged in the Japan seas by Mr. A. Adams. 
277. Trochus lividus, C. B. Ad.,= Modulus disculus, M. 403. 
280. Trochus reticulatus= Omphalius viridulus, M. 292. 
281. Turbo Buschit, C. B. Ad., = Uvanilla inermis, M. 287,= T. variegatus, Gray, MS. 
in Brit. Mus. The true U. Buschii is coloured outside like U. olivacea, but 
with a white base like U. znermis. St. Elena, Hds. in Brit. Mus. 
282. Turbo phasianella, ©. B. Ad., is probably the perfect form of Phasianella, Pyar.
