bo NERITINA. 



N. AVELLANA, Recl. PI. 25, figs. 52-55. 



Solid, irregularly striate, subopaque, somewhat shining, olive 

 grey, yellowish or orange-red, with articulated black bands; aper- 

 ture bluish white, columellar area minutely j^unctate, the margin 

 sinuous in the middle, and obsoletely dentate. 



Borneo, Formosa, Philippines. 



I fear that this will prove synonymous with the preceding species. 

 The synonyms are N. dubia, Issel (^=var. Isseliana, Martens) and 

 vars. 2)6tholata, and cJdorostida, IMartens. 



N. FABA, Sowb. PL 25, figs. 57-60. 



Solid, irregularly striulate, shining, yellowish or reddish, more 

 or less interruptedly strigate or reticulated with chestnut or black, 

 sometimes black-banded ; aperture bluish white, columellar margin 

 scarcely sinuous in the middle, obsoletely dentate. 



Diam. 15 mill. 



Western part of the Indian Archipelago, Singapore, etc. 



My only specimens of this species, types from its author, strongly 

 indicate identity with N. Soiverbyana. N. Baliensis, Mousson, and 

 the color-varieties strigosa, sagittata and fasciata. Martens are 

 synonyms. 



N. iNTERRUPTA, Recluz. PI. 25, fig. 56. 



Solid, striulate and occasionalty subplicate, yellowish, with fine 

 olivaceous somewhat anastomosing longitudinal lines, often interrupt- 

 ed partially, 'to form lighter colored spiral bands, young shells 

 frequently and old ones occasionally with several short spines above- 

 aperture bluish or yellowish, the columellar margin dentate nearly 

 throughout, with stronger teeth at the extremities of a central sinus, 

 area subrugose and minutely punctate, usually tinged with bluish 

 black behind ; often the base of the shell has a jet-black fasciole. 



Diam. 9-16 mill. 



Philippines; New Caledonia. 



Von Martens considered the species of Recluz a synonym of N. 

 avellana; on the contrary it ap]3ears to possess all the characters of 

 the more recently named New Caledonian N. nucleolus, Morelet, 

 (fig. 63). N. plieata, and N. Pazii, Gassies, and var. spinifera. 

 Martens are synonyms. The unfigured N. costulata and ^V. Artensis 

 of Gassies, likewise New Caledonian, are probably to be added.
