more than twice as high as that which precedes it. The test also is rather 

 thick. 



So far as can be ascertained from such an imj^erfect specimen, this 

 species seems to be nearl}- related to such shells as the Melania Heddiny- 

 foiiensis of Sowerb}',* to the Chemnitzia Athleta\ D'Oi'l)igny, and to other 

 similar species described by the latter writer. iSowerly, indeed, describes 

 his M. Heddingtonensis as having an infra-sutural carina, but that character 

 is so often absent that it is not represented at all in an}' of the tive tigures 

 of the species in the " Terrains Jurassiques." 



The genus Pseudomelania was constituted by P. I)e Loriol for the recep- 

 tion of the large, smooth and elongated Oolitic fossils formerly referred to 

 Melania and latterly to Chemnitzia. The so called Chemnitzioi of the 

 Mesozoic rocks may have had tolerably near aflfinities with such genera 

 as Eulima or Eulimella, but scared}' with the minute recent shells, with 

 cancellate sculpture, once refei'red to Chemnitzia but now usually included 

 in Eisso's genus Turbonilla. 



The nearest Cretaceous representatives of this species are the Turritella 

 Renauxiana and Eulima amphora of D'Orbigny.

The IVagment represented on Plate IX agrees remarkably well, so far 

 as it goes, \vith D'Orbigny's descriptions and figures of the Scalaria Al- 

 bensis, a Lower Neocomian fossil from the Department of Yonne, in 

 France. The original diagnosis of that s^jecies is as follows: — " S. testa 

 turritii, ini])erforata, transversim tenuiter striata, longitudinaliter costata: 

 costis Hexuosis, obtusis, antice jjosticeque evanescentibus; spira angulo 

 l.j", ultimo anfractu non carinato; apertura subrotundata." The mouth 

 ot the only specimen from the Queen Charlotte Islands is broken off, but 

 otherwise the characters of both seem identical. 



On the other hand, there is reason to doubt whether some of the Creta- 

 ceous shells placed by D'Orbigny in the genus Scalaria really belong to 

 the family Scalidee. In an article on Cretaceous G-asteropoda, contributed 

 to the " Geological Magazine," for March, 1876, the author, Mr. J. Starkie
