106 F. R. Cou-per Heed — Seclgicick Museum Notes. 



J. H. Cooke recorded the remains of Stereodon meJitensis from Malta 

 (1891); E. T. Newton wrote on Onychodus from the Old Red of 

 Forfarshire (1892) ; H. Bolton on Listracanlhus spinatus from the 

 English Coal-measures (1896) ; E. D. Wellburu on Bhadinichthys- 

 from the Coal-measures, Yorkshire (1900), and the fish fauna of the 

 Millstone Grit (1901). Lastly, Professor C. li. Eastman wrote on 

 a new Edestus-like form of fish-dentition named Catnpyloprion, from 

 the Coal-measures of Nebraska, U.S., 1902.

New Fossils from the Haverfordwest District. 



THE recent gift to the Museum of a fine series of Lower Palaeozoic 

 fossils from the Haverfordwest area by Mr. V. M. Turnbull, M.A., 

 who has personally collected them with much care, has at length 

 provided us with the means of determining many of the interesting 

 species which were mentioned without specific names (on account 

 of their imperfect preservation) by Messrs. Marr and Eoberts in 

 their paper on this district.^ The collections from which their lists 

 were drawn up are in the Sedgwick Museum. 



Several species new to science or to the locality can now be 

 accordingly described, but others must still await the acquisition of 

 better material. 



I. Phacops Robertsi, sp. nov. (Plate V.) 



A large number of specimens of a species of Phacops were 

 collected by Messrs. Marr and Roberts from the Sholeshook Lime- 

 stone and Redhill Beds, but the material was scarcely good enough 

 for a sufficient diagnosis of specific characters. Mr. Turnbull's new 

 specimens of the same form have now supplied this want. 



Description. — Head-shield nearly semicircular or broadly para- 

 bolic, obtusely pointed in front, about twice as broad as long, gently 

 convex from back to front, strongly convex from side to side with 

 the cheeks bent down ; anterior border present. 



Glabella elongated, expanding gradually towards the front to 

 about double the basal width ; rather narrow in relation to head- 

 shield, the base being only about a quarter its width ; nearly three 

 times as long as wide at base ; sides nearly straight behind frontal 

 lobe, converging posteriorly at about 20° ; gently and uniformly 

 convex, rising but slightly above cheeks. 



Frontal lobe of glabella not reaching front margin of head-shield; 

 with rounded lateral angles projecting slightly at the sides; about half

 " "Woodwardian Museum Notes " will in the future he continued under the title 

 of " Sedgwick Museum Notes," in consequence of the removal of the geological 

 collections at Cambridge to the new Sedgwick Memorial Museum.
