MIOCENE MOLLUSCA AND CRUSTACEA. 131 



Judging from the condition of the remains of tliis species I tliink it 

 may have been a rather thin and fragile shell, as the specimens are flattened 

 and cnished almost out of shape. The volutions have been highly convex 

 and rather short, somewhat more so than would be indicated by Mr. 

 Say's figTU'e above cited, while the stiise. would seem to have had flattened 

 interspaces, the striae themselves being distinctly raised lines of nearly equal 

 width with the interspaces. I should suppose from the specimens seen that 

 it would properly belong to the genus Mesalia Gray.

It does not appear that any aescription of this genus was ever pub- 

 lished by ^Ir. Conrad. The nearest approach to one is the simple compar- 

 ison with Sei'pula and Petalocouchus of Lea, made on p. 78 of the Miocene 

 Fossils, which is as follows: "This genus differs from Sei'pula in ha^'ug 

 septa, and from Petalocouchus Lea in wanting the revol\-ing plates." The 

 bodies to which he applied the name are contortedly coiled tubes, closely 

 resembling those of Sei-pula, or are like those of Yennetus, except that they 

 do not form regular volutions dming the earlier stages of then* growth, as 

 do those shells. They appear to have been adherent to foreign bodies, and 

 to have foiTned straight tubes, or to have had a laterally spiral fonn for a 

 time, after which they gi'ew in an in-egulai'ly coiling manner. The distin- 

 guishing featm-e, however, is that of ha\-ing the tube di\-ided into chambers 

 as it advanced in length, by deeply concave or "vaulted septa" at in-eg- 

 ulai- distances. The first impression one receives of the shell is that it 

 belonged to an annelid, and not to a ti-ue moUusk. This would appear
