bles the species of Euchelus, and especially the subgenus Perrinia, 

 which I also dredged from deep water in the same locality. I 

 have named the genus from Mino-Sima, the little island near 

 Niphon, in the vicinity of which favourable circumstances en- 

 abled me to glean, by deep-water dredging, much fragmentary 

 knowledge of the malacology of the Japanese archipelago. 



Minolia punctata, A. Adams. 



M . testa helicoidea, macromphala, fulva, rufo-punctata ; anfractibus 

 6y, convexis, cingulis transversis granulosis, majoribus cum mi- 

 noribus alternantibus, rufo-punctatis ornatis, interstitiis lamellis 

 tenuibus obliquis pulcherrime clathratis ; suturis canaliculars ; 

 umbilico perspectivo, cingulis granulosis concentricis instructo, 

 interstitiis concinne clathratis. 



This is another modification of the hollow spiral cone of the 

 Trochoid family; the whorls are somewhat loosely rolled on 

 themselves, which causes the sutures to be very deep, and the 

 last whorl at the peritreme to be almost disunited from the 

 penultimate whorl. The red-brown spots on the beaded ribs, 

 and the exquisite clathrate sculpture of the surface, render 

 this one of the prettiest shells in the great family of Trochoid 

 Scutibranchs. In texture it resembles Enida Japonica and 

 Turcica monilifera, and, judging from the shell, it appears to be 

 more closely associated with the Zizyphinus group than with 

 Gibbula or Margarita.

Part V. The Foraminifera enumerated by Denys de Montfort. 



Denys de Montfort, being desirous to do justice as far as 

 possible to the elucidation of the * Microscopic Shells * in his 

 systematic and illustrated work on Conchology*, introduced the 

 figures and descriptions of several Foraminifera into his book, 

 stating that he was far from pretending to have given all their 

 genera, but that he aimed at making some at least of their sin- 

 gular forms better known to naturalists (Discours preliminaire, 

 p. xxviii). To this end he figured some specimens apparently

 tions caracteristiques, leurs noms ; ainsi que leur synonymie en plusieurs
