Hah. Nearly all seas. (M., L., Jn., W.) Everywliere ; 

 very abundant. 



300. Scalaria aspera, 1897, Watson, anfea, p. 251. 



301. Scalaria clatliratula, 1798, Gr. Adams, Micr. xiv. 19 : Grwya 



Jeffreys, B. C. iv. 96; &Y. 210, Ixxi. 5. — McAudrew gives 

 this species from the Canaries, but not as, Dr. Jeffreys 

 {cf. ref.) says, from Madeira, nor does any other collector 

 seem to have found it. I got only ten young specimens 

 from deepish water at five stations along the South-east 

 coast from Funcbal to Punta de Sao Lourengo and from 

 Porto Santo. 



302. Scalaria cochlea, 1844, Gr. B. Sowerby, Tbes. Conch, i. pt. 4, 

 p. 103 bis, XXXV. 142 ; Dunker, Moll. Guinea, p. 18, ii. 

 46-48. (M., L., Jn., W.) Paiil do Mar, Puncbal ; Punta de 

 Sao Lourengo ; Porto Santo. Kare. 



303. Scalaria communis, 1819, Lamarck, An. s. Vert. yi. 2nd pt. 

 p. 225 ; Desbayes, Encycl. Method, iii. 951, pi. ccccli. 3 ; 

 Gwyn Jeffreys, B. C. iv. 91, ii. 3 ; & v. Ixxi. 3. Hah. From 

 JN'ortb Norway to the Mediterranean and the Canaries. 

 (N., "W.) Two bought specimens ; having these, and con- 

 sidering the distribution of the species, I give it here on 

 the authority of Seuhor Nobre. 



304. Scalaria commutata, 1877, Monterosato, Ann. Mus. G-enov. 



IX. 420 ; Kiener, Coq. Viv. ix. pt. 2, pi. iii. 9 (as S. mono- 

 cycla, but not that of Lamarck); Philippi,Enum. 1. 167, x. 2, 

 II. 145 (as S. pseiodoscalaris, but not that of Brocchi) ; 

 Sowerby, Thes. i. pt. 4, p. 101, xxxvi. 131, 132, 134 (as 

 S. claihrus, but not of Linne). Hah. From Normandy to 

 Mediterranean. (L., JST., Jn., W.) Porto da Cruz, Porto 

 Santo. Neither common nor abundant. — The separation 

 of this species from S. pseudoscalaris, Broc, is hardly 

 justified by the absence of spines at the top of the 

 longitudinal ribs ; there is an indication, though weak, 

 of such a development in the Madeiran form. 



305. Scalaria Mscheri, 1897, "Watson, antea, p. 252. 



306. Scalaria formosissima, 1884, Jeffreys, ' Lightning ' and

 Conch. IX. 62, xvii. 34. Hah. Porcupine Bank and Agores ; 

 North Atlantic, 340 to 1514 fms. (L.) Two specimens, 

 without record of locality.
