169. Pleurotoma discors, C. B. Ad., is probably a finely developed var. of Z>. 



aterrima. 



182. Pleurotoma rustica, C. B. Ad., = worn specimens of D. Melchersi, no. 164. 

 191. Manqelia neglecta, probably M. acuticostata, M. 473. 

 194, 195, 201 belong to Cerithiopsis. 

 196. Cerithium famelicum must stand for the "West Coast Uncinoids, M. 383 ; tbo 



Cumingian shell, and two out of ten in the type-series, belong to C. me- 



diolave, M. 382. 

 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 Triforis alternatus, no. 207. 



209. Both the specimens are dextral,= Cerithiopsis tuberculoides, M. 557. 



210. Turritella Banksii, C. B. Ad. (non Rve.} = T. goniostoma, jim., M. 379. 

 217. A dead, stunted specimen of Ccecum undatum, M. 371. 



220. Chemnitzia acuminata is a very broad but typical species ; not Clirysallida. 



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 clathratida, 



M. 513 and Mus. Cum.,+ CAr. communis + Chr. effusa, M. 510,+ Dunkeria 

 subanyulata, 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, + jDww- 

 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. ?similis, M. 520, which per- 



haps = Panamensis, var. 



230. Chemnitzia turrita^ZSl, " Rissoa, sp. ind." 



231, 235, 237, 238. These species of " ?Litorina " belong to Fossarus. 



233. Litorinaatrata-\- (adult) 257, ?Adeorbis abjecta, are the same (variable) species 



of Fossarina, A. Ad. 



239. Litorina parvida, C. B. Ad. (non Phil.),=Z. Philippii, M. 398. 

 244. Rissoa Jirmata+()\mJ) 250, R. scaliformis=jRissoina, sp. M. 409. 

 246. ?Rissoa inconspicua, C. B. Ad. (non Aid.), does not accord with the diagnosis, 



but is identical with Akania tumida, M. 414. 

 249. Rissoa notabilis -\-Cingida ?turrita belongs (with 252 and 254) to another 



suborder, =Parthenia quinquecincta, M. 498. 



252. VCinffula inconspicua= CJirysallida ovulum, M. 512. 



253. Cingula paupercula = ? Odostomia mamillata, M. 492, = Diala. 



254. Cingula terebellumParthenia exarata, M. 501. 



261. Vitrinella minuta. The original type accords better with Ethalia. 

 266. Vitrinella regularis is also an Ethalia. 



269. Vitrinella valvatoides. Probably an Ethalia. 



270, 271. Are apparently vars. of Solarium granulatum. 



272. May be distinguished as loyinia rotundata, frtfni its great superficial resem- 

 blance to Helix rotundata. 



275. Trochus Leanus is a pale var. of Calliostoma M'Andreee. 



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 re1iculatus= Omphalius viridulus, M. 292. 



281 . Turbo Buschii, C. B. Ad., = Uvanilla inermis, M. 287, = T. varicgatus, Gray, MS. 



in Brit. Mus. The true U. Bmchii is coloured outside like U. olivacea, but 

 with a white base like U. inermis. St. Elena, Hds. in Brit. Mus. 



282. lurbo phasianetta, C. B. Ad., is probably the perfect form of Phasianclla } ?var.
