We have much pleasure in dedicating this sj)ecies to our excellent 

 friend the Rev. W. L. T. Garnons, F.L.S. &c. 1'he laljour 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 wlience 

 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 stibelongato-turritd, multi- 

 cingulatd ; ulbd, cingulis nigro-macnlatis, maculis grandibus et 

 parvis, numerosissimis, anfractibus convexis, suprH et infra f usco- 

 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 upjjcr portions in this, and the 

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

 short, and presents a great peculiarity of character.

 fractu ultimo zond fused cingulato ; canali brevissimo ; columelld 

 albd, superne callosd ; apertura fauce albo. Long. ^ ; 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. tcstd arcuato-fusiformi, tenui, in- 

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

 carind maculis f us cis regularibus ornatd ; lahro externa rotunduto 

 ab anfractu ultimo sinu luto separate ; canali gracili, arcuulo, 

 spirce longittidinem ccquante. Long. lj|; lat. ^ ])oll. 

 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 shij) ' Sulphur,' a zealous and intelligent concho- 

 logist.
