Goofe. Scaliger alfo defcribes this ( fuppofed ) Bird within 
this (hell, (a) And with rcfpect to fo worthy a Perfori as ( a ) Excvc\l 
Sir Robert Moray ( who never meant to deceive) I my felt 5P« toward 
was once induced to publifh his Defcription of the fame, (b) (bymhr. 
But having examined the Shell it felt, I am of Opinion, i™^ 1 - N ° 
That all that is faid of a Bird, is fabulous. Bartholine (c) (<o m\ou 
would have it to belong to a kind of Can eel! as. But I rather Cent ' 6 ' 
agree with Columnafh&t it is a fort of Centre-Shell 5 as being 
fixed in like manner upon it's Bafe,md compofed of feveral 
fhelly parts. 
Of thefe Shells two Species are here preferved. One of 
them confifhng only of five fhelly pieces. Two greater, 
almoft like little Mufcle-fhells. To thefe are joyned, edge to 
edge, and oppofitely, a much Idler pair, fc, 111 fuch manner, 
as their Bafe (lands over the Cone, and their Points defcend 
half way towards the Bafe, of the greater pair. Both thefe 
pairs are on one fide hemci in with a fifth piece , narrow, 
long, and inwardly Concave, aimed like a Larks Heel. The 
Neck to which they arc faftend is here wanting, This Spe- 
cies is figured, and in fome fort defenbed by Wormius. But 
the Figure in Calceolarias' $ Mufaum anfwers not. 
The FLAT CENTRE-SHELL with the Scaled Bafe, 
Balanus comprejfa ($t Squamata 3 fo I call it. This Species 
c is in fome fort figur'd by Rondeletius. But his Defcription 
worth nothing. 'Tis near an inch long, and \ of an inch 
broad at the Bafe, where it is fome what narrower than 
in the middle. Whitifh, and with fome Rays of blew. It 
confifts of five greater pieces, whereof the middlemoil 
pair, the greater! and the longcft. The leifer pair are joyned 
to them edge to edge, reaching halt their length, but not 
oppofitely with their Points downward, as in the former 
Species,but upward. The fifth piece not joyned to this lefler 
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, (land 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 $ of an inch over 3 an inch, fometimes more , or 
lefs, in length 3 of a brown colour,rough, and compofed of 
an innumerable company of fmall Knobs,almoft like thofe 
on fome Filhes Skins. Several Shells, by the like Necks, 
commonly grow all together in a Clufter. I have
