At Ftg. 9. h one of thefe Infers completely ex- 
tended at its whole Length ; wherein it appears, that 
the Head is cover’d with a Shell or Cruft confining of 
three Parts; the middle Part is broad and round, a. 
which I (hall therefore call the Nofc : The two fide 
Pieces are of a triangular Form, b. b. in each of which 
is fituare a large protuberant Eye, c. c. The anterior 
Part of the Whole is encompafled by a round Bor- 
der, d. d. d. which looks like an upper Lip ; tho’ I 
do not take it to be fo; but that the Mouth is fitu- 
ate lower down, as in the Crab-kind, and does not ap- 
pear in any of the Specimens I have yet feen. On 
each Side the Crown of the Head, towards the back 
Tart of it, are two fmall Knobs, e. e. At f.f in 
Fig. 10. appear fome Traces of Feet, which feem 
to lie under the Belly: But, as the Belly, or under 
Side, was not diftind, not being cleared from its 
ftony and earthy Matter, I could not difeern any 
other Legs. 
It is moft likely the whole Back of this Creature 
was, when alive, cover'd with a Cafe, or undivided 
Ely tram, as is the Scolopendra aquatic a feutata, 
deferibed in thefe Tranfatlions , n. 44.7. p. 1 70, and 
173. by M. Klein, of Dantzick', and afterwards by 
the Rev. Mr. Littleton Brown, both worthy Mem- 
bers of this Society. M. Klein fays, the Cafe was 
whole; and that he was forced to flit it open to 
fhew the Back underneath ; when it appears, that the 
Body was trilobated, as in Fig . 9. The Cafe, being 
very thin and tender, may probably have been bro-
