Goofe. Scaliger alfo defcribes this ( fiippofed ) Bird within 
this (hell (a) And with rcfpecl to fo worthy a Perfon as ( a ) Exerdr, 
Sir Robert Moray ( who never meant to deceive) I my felf 5 ?; t0 J M 
was once induced to publifh his Defcription of the fame, (b) (bypwoC. 
But having examined the Shell it felf, I am of Opinion, Tranfaa. n, 
That all that is faid of a Bird, is fabulous. Bartholine (c) U) Kiiior. 
would have it to belong to a kind of Cancellus. But I rather Ccnt ' 6 ' 
agree with Columnaj&m. it is a fort of Centre-Shell 5 as being 
fixed in like manner upon it's Bafe&nd compofed of feveral 
fhelly parts. 
Of thefe Shells two Species are here preferved. One of 
them confining only of five fhelly pieces. Two greater, 
almoft like little Mufck-Jhells. To thefe are joyned, edge to 
edge, and oppoiitely, a much lefler pair, fc. 111 fuch manner, 
as their Bafe ftands over the Cone, and their Points defcend 
half way towards the Bafe, of the greater pair. Both th^fe 
pairs are on one fide hem'd in with a fifth piece , narrow, 
long, and inwardly Concave, almoft like a Larks Heel. The 
Neck to which they are faitcn'd is here wanting. This Spe- 
cies is figurd, and in fome fort defer i bed by Wormius. But 
the Figure in Calceolarias' s Mufaum anfwers not. 
The FLAT CENTRE-SHELL with the Scaled Bafe, 
Balanus comprefa & Squamata 5 fo I call it. This Species 
is in fome fort figur d by Rondeletius. But his Defcription 
worth nothing. 'Tis near an inch long, and 4 of an inch 
broad at the Bafe, where it is fomewhat narrower than 
in the middle. Whitifh, and with fome Rays of blew. It 
confifts of five greater pieces, whereof the middlemoft 
pair, the greatelt and the longeft. The lelfer pair are joyned 
to them edge to edge, reaching half their length, but not 
oppofitely with their Points downward, as in the former 
Specie sfaut upward. The fifth piece not joyned to this lelfer 
pair, as in the other Species, but to the oppofite edge of the 
greater. Round about the Bafe of the Shell feveral little 
pieces, fome bigger and fome lefs, Hand after the manner 
of Scales, with their points alfo forward. So that it looks 
almoft like a great Bud crufhed flat. 'Tis joyned to a Neck^ 
about i of an inch over 5 an inch, fometimes more , or 
kfs, in length 3 of a brown colour,rough, and compofed of 
an innumerable company of fmall Knobs,almoft like thofe 
on fome Fifties Skins. Several Shells, by the like Necks, 
commonly grow all together in a Clufter. I have
