368 PHILOSOPHICAL TRANSACTIONS. [^ANNO ISQQ. 



A Supplement to the Account of a Scolopendra Marina, &c. Described in 

 N" 225 of these Transactions. By Dr. Tho. Molyneux, F.R.S. N°251, 

 p. 126. 



I find a letter (Phil, Trans, N° 249) of Mr. Dale's to Dr. Lister, wherein he 

 mentions the scolopendra marina I gave an account of, N° 225 of the Trans- 

 actions, as described by Rondeletius, under the title of Physalus, in his book, 

 De Piscibus ; but I must crave leave to differ from him in opinion as to this 

 particular : for I conceive that author could not understand by the name of 

 physalus, what I mean by scolopendra marina, e mare Hibernico, &c, but 

 some other marine animal, as the descriptions are quite different. From whence 

 I think it is very plain that Rondeletius's physalus, and the scolopendra marina 

 described by me, are quite different species of animals. But I confess Mr. 

 Dale was thus far in the right, though he seems not to have known it himself, 

 that the scolopendra marina I mention has been noticed by others, before I 

 spoke of it ; for upon further inquiry, since my writing that account, I meet in 

 the Acta Medica et Philosophica Hafniensia, of Thomas Bartholine, vol. the 

 3d, p. 87, the figure of a sea-insect found at Katwick-up-Zee in Holland bn 

 the strand, and communicated to the publisher by Oligerus Jacobeus, who 

 gives it the name of vermis aureus vel species eructe marinas rarior ; which I 

 am confident is the same with the scolopendra marina e mare Hibernico, &c. 

 though Bartholine's figure is faulty, and the description short, false, and im- 

 perfect. And I am likewise apt to think, that Ulysses Aldrovandus, in his lib. 5, 

 De Insectis, cap. 15, p. 636, designed our scolopendra by his first figure in that 

 chapter, where he calls it scolopendra marina lato corpore subcastaneo velut 

 pedibus innumeris longiusculis aurei coloris, and says no more of it ; but his 

 icon is much worse than Bartholine's. 



An Abstract of an Account of Five Pair of Muscles, which serve for different 

 Motions of the Head; on the First and Second Fertebrce of the Neck ; and of 

 Two Ligaments, one of luhich fastens the Head to the First Vertebra, and 

 the other fastens the First to the Second. To tvhich is annexed the History of 

 an uncommon Appearance of a Human Skull. By M. Dupre, Surgeo?i to the 

 Hotel Dieu in Paris ; with Remarks by JVilliam Cowper. N° 251, p. 130. 



This tract, lately printed in French, was sent to Dr. Lister. The author 

 seems to put a value on it, and expresses his surprise that such obvious organs 

 should escape the observation of anatomists : he hopes these discoveries will 

 excite a noble emulation in those of his profession.
