74 SOWERBY : REVIEW OF THE GENUS PVRULA. 



Pyrula reticulata, Lamarck. 

 Synonymy. P.ficoides, Lam., P. clathrata, Rousseau, P. foriior, 

 Morch, P. decussata, Sowerby, as of Wood (Thes. Conch., vol. iv, 

 pi. 423, figs. 1 and 3. not fig. 2). The more prominent spiral ridges 

 of this species are much closer than in P. decussata. It inhabits 

 various parts of the Indian Ocean as far as Japan, and a small 

 prettily-coloured variety is found on the Mauritian Coast. 

 Pyrula decussata, Wood. 

 Synonymy. P. ventricosa, Sowerby, P. reticulata, Sowerby, as of 

 Lamarck (Thes. Conch., vol. iv, pi. 423, figs. 6 and 7). 

 Distinguished from all the other species by its distant spotted spiral 

 ridges. Tryon gives the locality : " Panama to Cape St. Lucas, 

 Lower California.'' 



Pyrula papyracea, Say. Em. {papyratia). 

 Synonymy. P. gracilis, Philippi, P. reticulata, Sowerby (Genera 

 of Shells). This species has been overlooked by various authors, 

 being probably taken for P. dussumieri, which it resembles in form. 

 No mention is made of it in the Thesaurus Conchyliorum. It, 

 however, appears to be a good species, inhabiting, according to 

 Tryon, Beaufort, N.C, to West Indies. It is more coarsely sculptured 

 than P. dussumieri, and of a narrower form than P. reticulata, 

 usually very pale in colour, almost white, but brown within. 

 Pyrula dussumieri, Valenc. 

 Thesaurus Conchyliorum, vol. iv, pi. 425, fig. 5. Synonym. 

 P. elongata, ( iray. A species of very graceful form, narrow, tapering, 

 finely ridged and delicately painted, with light brown undulating 

 streaks. Habitat : China Sea. 



Pyrula tessellata, Kobelt. 

 Kuster (Picula), plate 2, fig. 3. Synonym, P. reticulata var. 

 Sowerby, Thes. Conch., vol. iv, pi. 423, fig. 2. A very pretty 

 and easily recognised Australian species. It is smaller than any of the 

 others and nearly white, ornamented with rows of rather distant brown 

 spots. It has been erroneously taken for the P. gracilis, Philippi. 

 Pyrula filosa, Sowerby, nov. sp. 

 Testa pyriformis, solidiuscula, dilute fuivescens, transversim 

 fusco lincata ; spira breviter couica, apice obtusiuscula ; 

 anfractus 5, convexi, spiraliter lirati, longitudinaliter filo-striati ; 

 anfractus ultimus ventricosus, tiris angustis numerosis parum 

 elevatis, alternatim fuscis, striis filiformibus cancellatis sculpfus ; 

 apertura lata, faucc fusco tincta : columella sinuosa ; peristo7na 

 simplex. 

 Long. 80, maj. diam. 48 millim. 

 Habitat: Hong Kong, China.
