 SPIRULA. 



GE\ERIC CHARACTER: The shell cylindrical, thin, 

 nearly transparent, many chambered, partly turned into 

 a discoidal spiral form; the whorls separate, the last 

 produced in a straight line. Partitions transverse, equally 

 distant, externally concave ; syphon lateral, interrupted ; 

 aperture round.

 According to Dr. Fleming, two specimens only of this 

 shell are recorded as British; having been found on the 

 coast of Ireland. I have been informed of several, taken 

 on the coast of Cornwall, and three specimens have come 

 into my possession, that were found within a mile of my 

 own residence; but they were destitute of an inhabitant, 

 and one is shewn to have been for some length of time 

 dead, by having attached to it the shell of a small Spirorbis. 

 They were probably floated to us in the same manner as 

 the Ianthina, as before noticed ; and whether the animal 

 has lived in our waters is still a matter of doubt. 



The Second Division includes no British Shell.

REPORT on the Zoology of the County of Cornwall, presented 

 (with some alteration) to the Meeting of the British Association 

 of Science, at Plymouth, in the year 1841, forming an appendix 

 to the preceding Fauna. 



The Report of the Zoology of the County of Cornwall 

 now presented to the British Association of Science, is de- 

 signed to afford a summary of the species, chiefly of the 

 Vertebrate, Radiate and Testaceous classes, with the stalk 

 eyed genera of Crustaceans, and so many of the Zoophytes 

 as have been recognized by naturalists: reserving for further 

 consideration the species concerning which there is any 

 doubt. It is intended also to comprize such as have been 

 discovered since the publication of the former portion of the 

 Cornish Fauna. 



Of the fourteen or fifteen species of Cheiroptera (Bats) 

 enumerated as British by Mr. Bell, six are included in the 

 Cornish Fauna; and one more (Vespertilio Discolor) has 

 been found at no greater distance than Plymouth. Of the 

 remainder, eight are too limited, in numbers and destribution f
