Species of Marine Shells. 185 



to which this sliell bears a sufRcientlj close resemblance for 

 comparison. 



In writing the diagnosis of the type specimen I have said 

 that the lira^. of the last whorl are duplicated, or divided by a 

 groove, but I find this is not a constant character. 



Calliostoma Nevtlli, sp. n. 



Testa conica, solidiuscula, imperforata, albida, fulvo radiata ; spira 

 elatiuscula, acuta, vix convesa ; anfractus 7, planato deelives ; 

 liris 7, confertis conspicuo granatis spiraliter cingulati ; inter- 

 stitiis angustis, fulvis ; sutura inconspicua ; anfractus ultiraus 

 curtus, obtuse angulatus, supra angulum levissime convexus ; 

 basis planato convexa, liris granatis 8 instructa ; columella brevis, 

 crassa ; apertura oblique subquadrata, intus laevis ; labrum creuu- 

 latum. 



Alt. 7|, maj. diam, 7 mm. 



A regularly conical shell, the whole surface of whicli is 

 covered with closely and beautifully beaded spiral ridges. 

 The base is not so flat as in the preceding species, and the 

 spire less elevated. 



The shell bears some resemblance to C. scohinatiim [Zizl- 

 phinus scobinatus, Reeve, as of A. Adams), but it is more 

 broadly conical, and the bead-liiie pustules are larger and 

 closer together. Compared with C. fragum, Philippi, it is 

 also broader, and the beaded ridges are closer together and 

 more numerous, with very narrow interstices. 



Clanciilus crasstlabrum, sp. n. 



Testa turbinata, subovalis, anguste perforata, crassa, albida, maculis 

 paucis pallide fulvis eonspersa ; spira elata, leviter convexa ; 

 anfractus 41, primus laevis, rotundatus, sequentes convexi, rotun- 

 dati, dense grano-lirati ; liris 8, craasis, pustulis numerosis con- 

 fertis gemmuliformibus ornatis ; interstitiis angustis, crenulatis; 

 sutura inepte canaliculata ; anfractus ultimus rotuudatus, liris 

 pustulosis circ. 15 instructus ; apertura rotundata ; labrum 

 crassum, crenulatum, intus valde liratum ; columella breviter 

 expansa, planulata, bidentata, dente postico late rotundato, 

 autico oblique elongatim producto. 



Alt. 7, diam. 6^ mm. 



A shell of an unusually oval form for the genus, approach- 

 ing some of the forms of Euchelus, the surface being similar 

 to that of the much larger Euche/us haccafus, Menke. it has 

 a much smaller umbilicus than is common in the genus 

 Clnnculus, and is further distinguished by its narrow 

 obliquely-produced anterior columellar tooth.
