MARINE MOLLTJSCA OF MADEIRA. 311 



Rissoa parva, 1778, da Costa (as Turbo), Brit. Conch. (W.) Funchal, 

 50 fms. Two rubbed and broken specimens, doubtless not Madeiran, 

 but brought in ballast. 



288. Rissoa (Cingilla) picta, 1867, Grwyn Jeffreys, Ann. & Mag. 



p. 435 ; Watson, P. Z. S. 1873, p. 381, xxxv. 18 ; Wein- 

 kauff, Conch.-Cab. 2nd ed. i. pt. 22, p. 151, xviii. 10. (L., 

 Jn., W.) Everywhere in shallow water. Very abundant. 

 Rissoa (Sctia) pulcherrima, Gwyn Jeffreys; Watson, P. Z. S. 1873, p. 383, 

 is now suppressed. 



289. Rissoa {Pisinna) sabulum, 1842, Cantraine, Bull. Acad. 



Brux. ix. pt. 2, p. 348 ; Watson, P. Z. S. 1873, p. 387, 

 xxxvi. 25. Hah. Mediterranean. (L., Jri., W.) In 

 shallow water from Funcbal to Punta de Sao Lourenco, 

 Porto Santo, and the Selvagens. Abundant, but local. 

 — It seems strange that both this species and R. glahrata, 

 v. Miihl., should be identified with R. punctulum, Phil. 



290. Rissoa similis, 1836, Scacchi, Cat. Beg. Neap. p. 14 ; Wat- 



son, P. Z. S. 1873, p. 379, xxxiv. 16, 16 a (given then, as 

 now, in utter disbelief in the whole group into which 

 R. parva has been split, but given here because work such 

 as Baron Schwarz v. Mohrenstern's great Monograph on 

 the group cannot without impertinence be gainsaid except 

 by work of equal fulness and care. The species, as well as 

 the others of the group, is given here from his identification 

 of specimens from Madeira). Mediterranean. (L., Jn.,W.) 

 Everywhere, including the Selvagens. Very abundant. 



291. Rissoa (Setia) spadix, Watson, P. Z. S. 1873, p. 383, xxxvi. 



22 (as R. perminima, Manzoni). — Weinkauff, Conch.-Cab. 

 2nd ed. i. pt. 22, p. 149, quotes my paper &c. under 

 R. perminima, Manzoni, whose description he follows, but 

 his figure 8, pi. xviii., is a copy of the Madeiran species 

 now published (see Beeve, Conch. Icon, as, on my sug- 

 gestion (I. c), distinct) ; that is, the description refers to a 

 different species from that of the figure. I adopted in the 

 P. Z. S. paper of 1873 Dr. Grwyn Jeffreys's identification of 

 my Madeiran species. I am still, as then, unfortunately 

 without any specimens of Manzoni's Canarian species; but on 

 fresh and very careful review I am satisfied that Manzoni's 

 description will not cover the Madeiran species, and Mr. 

 Edgar A. Smith's opinion confirmatory of my own is adverse 

 to Dr. Jeffreys's identification. — (Jn., W.) Prom Punchal 

 to Punta de Sao Lourenco and Porto Santo. Not abundant.
