We have much pleasure in dedicating this species to our excellent 

 friend the Rev. W. L. T. Garnons, F.L.S. &c. The labour which 

 this worthy gentleman has bestowed on the arrangement of the 

 Woodwardian collection of shells at Cambridge bears ample testi- 

 mony of his zeal for the science. Several specimens have lately 

 made their appearance in London, but we are not aware from whence 

 they have arrived. The above locality is obtained from a single 

 specimen found by Mr. Cuming at that place, lying dead upon the 

 shore at low water. 



Pleurotoma spectabilis. Pleur. testd subelongato-turritd, multi- 

 cingulatd ; albd, cingulis nigro-maculatis, maculis grandihus et 

 parvis, numerosissimis, an/ractibus convexis, suprd, et infra fusco- 

 fasciatis ; canali brevi, leviter flexuosd. Long. 2^; lat. ^ poll. 

 Hab. Island of Ticao, Philippines (on the reefs). 

 The spotting is of a more numerous and miscellaneous character 

 in this species than in any of the genus, though it presents in certain 

 respects a modification of that in the preceding species. The dusky 

 band which girds the lower portion of the whorls in that species is 

 exhibited both round the lower and upper portions in this, and the 

 number of spots is apparently doubled in like manner ; the canal is 

 short, and presents a great peculiarity of character. 



Pleurotoma exasperata. Pleur. testd turritd, anfractihus in

 fractu ultimo zond fused cingulato ; canali brevissimo ; columella 

 albd, superne callosd; aperturiB fauce albo. Long. J ; lat. | poll.

This interesting little shell resembles the Pleurotoma unizonalis in 

 being surrounded with a single clear dark band ; but it differs, first, 

 in being of a more turreted form ; secondly, in having the whorls 

 encircled with a sharp row of tubercles instead of longitudinal ribs ; 

 and thirdly, in the columella and interior being white, whereas in 

 that species it is always brown. 



Pleurotoma arcuata. Pleur. testd arcuato-fusiformi, tenui, in- 

 jlatd, subpellucidd , anfractibus lineatis, in medio acute carinatis, 

 carind maculis f us cis regularibus ornatd ; labro externo rotundato 

 ah anfractu ultimo sinu lato separata ; canali gracili, arcuato, 

 spirce longitudinem cequante. Long. 1|^; lat. § poll. 

 Hab. Coast of Veragua, Central America. 



A few specimens only of this inflated transparent-looking shell 

 were collected at the above-mentioned place by R. Hinds, Esq., of 

 Her Majesty's ship ' Sulphur,' a zealous and intelligent concho- 

 logist.
