t Edward Lhwyd, or Lloyd, was born in 1670, and died in July 1709. He was 

 son of Edw. Lloyd of Kid well, in Caermarthenshire ; became, when 17 years of 

 age, a student of Jesus Coll. Oxford, and, upon the resignation of Dr. Plot, was 

 appointed keeper of the Ashmolean Museum. He was distinguished amongst his 

 contemporaries for knowledge in antiquities and natural history. "He is, indeed," 

 writes Archdeacon Nicolson, afterwards Bishop of Carlisle, and very competent to give 

 an opinion, " if I may judge of him, the greatest man (at antiquities and natural 

 philosophy together) that I have had the happiness to converse with." Letters to 

 Ji. Thoresby, F.R.S., vol. i. p. 206. Ray gratefully records his assistance in the 

 Synopsis and Hist. Plantarum ; and Petiver frequently mentions him as his 

 "worthy,'' " curious," and " generous friend." Of his life and writings the reader 

 will find an account inPulteney's Sketches of Botany in England, vol. ii. p. 110-116 ; 

 and some additional particulars in the " Analecta Scotiaa" especially in the Second 

 Series, published at Edinburgh in 1838. See also Wood's At/ten. Oxon. v. ii. 

 p. 1094 ; and Richardson's Correspondence, edited by D. Turner, p. 12. The genus 

 Luidia of Edw. Forbes is dedicated to his memory. See the Hist, of Brit. Star- 

 fishes, p. 136.
