490 //. Woodward — On a New Long-eyed Trilohite, 



At page 90, Mr. Salter writes of Calymene as follows : " One of 

 the most graceful and compact of all the Trilobite group ; the head 

 and tail well developed, but not extravagantly so ; the former with a 

 three-lobed glabella, very convex and narrowed in front, and with 

 prominent supine eyes, lohich have evidently a very thin cornea, in which, 

 only very rarely, the lenses are visible ; ^ a thick margin to the head, 

 the suture being in front submarginal and subtending a broad rostral 

 shield, etc., etc." The passage we wish to call attention to is 

 printed in italics. 



All collectors of Trilobites can corroborate the above observation 

 of Mr. Salter's; nay, more, it is rarely, if ever, that the cornea 

 itself is preserved in Calymene. 



Out of the numerous specimens which have come under my own 

 notice, I have seen but one. The specimen consisted of part of the 

 head of a small Calymene Bhmenbachii, carefully worked out by that 

 veteran collector of Dudley fossils, Mr. John Gray, of Hagley, some 

 of whose choicest specimens of Crinoids and Trilobites (beautifully 

 developed with his own hands) now adorn the Geological Gallery of 

 the British Museum.' 



The aspect which the eye ordinarly presents in Calymene is that 

 of a lenticular aperture, with a thickened and often considerably raised 

 margin, the smoothness of the edge of which depends — (certainly in 

 some out of the many specimens which I have lately examined) — 

 upon the skilful finish put upon it by the Dudley " Fossilists," who 

 have for many years pursued fossil-development as an important 

 branch of native industry.^ 



Knowing these things, it v^ill not seem surprising that I looked 

 with mingled feelings of interest and distrust at the " carte de visite" 

 of the remarkable Trilobite figured in the centre of our plate, and 

 desired, before all things, to see the original specimen. This was 

 duly sent me up, and I looked at it still more earnestly, and appealed 

 to other eyes than mine to examine it critically, and I am glad to 

 say that my colleagues all confirmed me in my decision of its 

 genuineness. 



In all points, except in the remarkable eye-peduncles, the speci- 

 men appears to be a true Calymene Blumenbachii (see Plate XXI. 

 Fig. 1). Indeed, there are specimens in the Museum collection 

 which match Mr. Hollier's Trilobite most exactly, save in this one 

 particular. 



1 could only call to mind one other instance of a Trilobite having 



^ " Hall, in his ' Pala30iitology of J^ew York,' has figured the lenses. I have 

 never scon any traces of them." — J.W. S. 



2 This little specimen was sent me privately in a letter by Mr. Gray, some long 

 time since, and, to my regret, I am unable at this moment to light upon it, or I 

 should have figured it on the accompanying plate. 



3 Mr. Gray informs me that for fifty years the miners have not only collected and 

 developed Trilobites, but even made them when they did not turn up in sufficient 

 abundance, lie adds, " New and undescribed species are still to be purchased, com- 

 posed of parts of Odymene and Phacops united together, either by accident or by the 

 aid of a knife and a little gum." I have myself seen (in the possession of Dr. 

 Grindi-od, of Malvern) an Ampyx nudus cleverly made out of the limestone with the 

 help of the tail of a Fhacops howningice.
