It would appear as if the present Bulimus (of which I have 

 not been able to procure a type for comparison), the B. tabidus, 

 and the B. Tarnerianus are so closely allied inter se as to be 

 barely separable from each other. I have already stated that, 

 judging from at all events the published diagnoses, the B. ta- 

 bidus does not seem to me to be distinguishable from the Tar- 

 nerianus ; and as regards the B. anaga, Mousson closes his 

 remarks concerning it as follows : 4 Cette particularity le rap- 

 proche du B. Tarnerianus, dont il ne differe que par sa forme 

 plus ventrueS And, with reference to the B. anaga as com- 

 pared with the tabidus, he adds ' Je dois un echantillon authen- 

 tique de cette espece a la bonte de M. Tarnier. On serait tente 

 de la joindre au B. tabidus, Shuttlw., dont il partage la forme 

 generale.' He then points out in what the B. anaga (judging 

 from the single type to which he had access) seemed to differ 

 from the tabidus, the main characters consisting, as it appears 

 to me, in the shell being ungranulated except at the base, and 

 in the connective lamina between the margins of the peristome 

 being developed (as is liable to be the case in nearly all the spe- 

 cies) into a small tubercle at the right-hand insertion. 



Bulimus obesatus. 



T. rimata, elongate oblongo-ovata, inflatiuscula, vix nitidius- 

 cula, grosse, dense, et irregulariter plicato-striata (striis haud 

 granulosis, et vix etiam interpunctatis), rufo-brunnea ; spira 

 subconcave ovato-conica, apice ipso prominulo-subpapilliformi ; 

 anfractibus 7, planiusculis sed sutura distincte incisa ; apertura 

 longiuscula, peristomate albo, expanse, acutiusculo, intus incras- 

 sato, marginibus distantibus, aut omnino separatis aut lamina 

 tenuissima junctis, basali cum sinistro vix angulatim continuo ; 

 columella elongata, subsinuata. Long. tin. 8 ; diam. maj. 4. 



examples in my collection belong nevertheless, most unmistakeably, to the 

 Twnerianus ; and indeed they were so labelled by Mousson himself in the 

 particular box which is appropriated to them, and which he afterwards re- 

 turned to me.
