1921 TULITIDM 43 



July 



XL, [xli], 2, as synonym of his P. kinkelini, but specific agreement seems 

 not quite satisfactory ; generic is possible, but without s.l. is not proved. 

 B. Phaulomorph. K. pendambilianum, Dacque sp., vi, 4, with 

 indication of a small lateral auricle. 



Family TULITIDM, nov. 



Cadicones passing to serpenticonic, directly or by way of sphaerocone 

 stage. The various genera to which species have been attributed by 

 authors indicate the changes of development and morphic equivalence. 

 Ornament of low relief, often of distant character, knobs on junction 

 of inner margin and venter, no real lateral area ; (OVL2) ; costae 

 cross venter, usually with marked forward sweep. All ornament passing 

 away, sooner or later, ventral ornament retained longest : the feebleness 

 of ornament and the passing to smoothness, even in cadicone stage, 

 characters of the family. Suture-line simple, of pattern of simple-lobed 

 Sphaeroceratidae, retraction of marginal portion only slight. 



Teloceras, Emileia and Ervmnoceras, or the coronates of the 

 families Stepheoceratidae, Sphaeroceratidae and Pachyceratidae, are 

 comparable — catagenetic development is similar. S.l. prevents associa- 

 tion with Stepheoceratidae ; character of ribbing does not concur with 

 Sphaeroceratidse — the sphaerocones of that and of Tulitidae are obviously 

 independent developments ; shape and s.l. have more suggestion of 

 Pachyceratidae, but the feebler development of ribbing, leading to 

 smoothness, the considerable sphaeroconic development and the difference 

 of s.l. — ES and Si about equal in depth, instead of decidedly unequal — 

 suggest the advisability of separation. The Tulitidae and the other three 

 families are all offshoots of a coronate cadicone radical, the Tulitidae 

 occupying a geological position between the Bajocian and the Callovian 

 coronates. .... 



England, Bathian (Falaisian), Fullers' Earth Rock of Dorset and 

 Somerset ; Great Oolite of Gloucestershire and Oxfordshire ; France, 

 Alsace (Schlippe) ; Deux Sevres, Vendee, etc., (Amm. bullatus and 

 microstoma, d'Orbigny, presumably belong to the family) : Germany, 

 Baden (Schlippe) ; Wurtemberg, various fof//a///s-like forms : Lithuania 

 (Siemiradzki). The family is of particular interest as showing the 

 contemporaneity of the Fullers' Earth Rock of South England with 

 the Great Oolite of Gloucestershire-Oxfordshire, and thus that the 

 Fullers' Earth Rock is later, not earlier, than the Stonesfield Slate. 

 Genera of the family occur in at least two distinct deposits of the Great 

 Oolite — the Minchinhampton Shelly Beds, which are oolitic, and another 

 bed of the same place, which is non-oolitic. In the same way they 

 mark at least two deposits of Fullers' Earth Rock — the brownish Milborne 

 Beds and the white Thornford Beds (S. Buckman, Brach. of Namyau 

 Beds; Pal. Ind. Ill (2), 1918, 237). 



Genera, Tulites, Tulophorites, Madarites, Pleuro- 

 phorites, Rugiferites, Sphaeromorphites, Bullati- 

 morphites, Morrisites, nn., with Morrisiceras, S. Buckman, 

 to be removed from the Sphaeroceratidae (T.A. Ill, 1920, p. 22). 



It is necessary to notice, as belonging to the Tulitidae, Morris & 

 Lycett's species, Ammonites subcontractus (Moll. Great Oolite, Pal. Soc, 

 1850, p. n, PI. 11, figs 1, id). The word species must be read in the 

 plural, for their figures " are composites, drawn from two different
