Plate 7, fig. 2; figure 16 



Camarophoria antisella BROILI, F., 1916, Perm. Brach. von Timor, p. 58, pi. 

 126 (12), fig. 1-3, 5 ; LICHAREV, B., 1934, Doklady Akad. Nauk, Leningrad, 

 vol. 1, No. 4, p. 211, 213. 



Shell moderately strongly biconvex ; outline rounded subpentagonal 

 to subelliptical, widest near or anterior to midlength ; anterior com- 

 missure strongly sulcate, lateral commissure smooth ; pedicle valve fold 

 fiat-crested, standing only slightly above flanks, crest slightly depressed 

 in some specimens, producing hint of costation ; brachial valve sulcus 

 depressed only near anterior of valve, curving to fill fold at anterior, 

 floor slightly convex or flat, with very low, short, rounded costa on 

 midline at anterior of shells with slightly depressed crest of fold ; shell 

 otherwise lacking radial structures or ornamentation; concentric 

 growth lines fine, closely and evenly spaced ; growth laminae somewhat 

 stronger, irregularly and more widely spaced, most frequent near mar- 

 gins. 



Pedicle valve with greatest convexity about one-third distance ante- 

 rior to beak, transversely rather evenly convex posterior to fold, more 

 steeply sloping lateral to fold ; beak short, sharp, strongly curved, sub- 

 erect or erect; delthyrium small, open, triangular, apparently without 

 deltidial plates, opening nearly directly dorsally; beak ridges blunt, 

 short. 



Brachial valve somewhat less strongly convex, greatest swelling in 

 umbonal region, strongest convexity longitudinally through sulcus ; 

 beak blunt, with apex in pedicle valve, somewhat constricting delthyr- 

 ium. 



Pedicle valve interior with broad spondylium elevated on high me- 

 dian septum duplex ; septum becoming thin and slightly higher toward 

 anterior edge, extending about one-fifth length of valve. 



Brachial valve interior with short thin hinge plate in apex ; cardinal 

 boss low, fimbriate for muscle insertion ; camarophorium thick in 

 posterior, edges touching hinge plate, posterior part elevated on thick 

 median septum duplex ; septum becoming thinner and much higher 

 anteriorly, extending about one-third length of shell, intercamarophor- 

 ial plate absent.
