I am a little doubtful whether the T. haliotidea of central 

 and southern Europe can be truly regarded as having established 

 itself at Madeira. It appears formerly to have occurred, though 

 very sparingly, near Funchal ; but I have no evidence that it 

 is still to be met with. Indeed the only three examples, so far 

 as I am aware, which have ever been observed in the island 

 were in Mr. Lowe's garden at the Levada de Sta. Luzia, now 

 many years ago, namely during February of 1830, 'crawling 

 about a small tank, after a long continuance of rain.' 



I have not myself had an opportunity of inspecting the 

 animal of the T. haliotidea ; but, commenting on the speci- 

 mens to which I have just called attention, as having been 

 found near Funchal in 1830, I possess an old note, made by Mr. 

 Lowe, to the effect that it is ' of a uniform pale clear buff- 

 yellow, except the edge of the foot which is tinged with pink or 

 flesh-colour. The disk of the foot beneath and the posterior 

 extremity behind the shell are of the same pink, or salmon- 

 coloured, hue. Two faint grooved lines, and a still fainter one 

 between them (making three in all), run down the middle of 

 the back which is also marked out from the sides by two 

 stronger grooved lateral ones, ascending upwards towards the 

 shell (much as in the T. Maugei) ; but this dorsal compartment 

 is not portioned out by coarse oblique grooves so as to become 

 uneven and tumid, or reticulated. The whole creature is more 

 slender than that of T. Maugei ; and the shell is of a uniform 

 horn-colour, the margin appearing, when the shell is in situ, 

 a little pinkish.' 



Although Albers has figured and described, in his ' Malaco- 

 graphia Maderensis,' both of the Testacellas which are here 

 enumerated, I have nevertheless refrained from citing his 

 monograph, because it appears to me that he has inadvertently 

 mixed up the characters of the two species, or at any rate has 

 interchanged their shells.
