T. cadus, n. Stephanoceras m.f. coronatum, Schlotheim, Bru- 

 guiere spp., Siemiradzki, (S. coronatum von Popilany ; N. Jahrb. 

 Min. 1882, ii, p. 255, fig. [2], p. 256). A massive cadicone of Teloceras 

 and, later, of Erymnoceras aspect, with no sign of degeneration. [Minchin- 

 hampton] Gloucestershire, Great Oolite, Shelly Beds ; S.B., ex J.B., 

 Coll. 2182 ; Holotype ; S. 77, 37, 85, 35 ; 125, 43, 86, 35 : " Sherborne, 

 Dorset " [Milborne Wick, Somerset] ; Fullers' Earth Rock (Milborne 

 Beds) ; S.B., ex Darell, Coll. 2760 ; Paratype ; S. 53, 36, 93, 34 ; 72, 36, 

 89, 35 ; about half-whorl body-chamber : Popilany, Lithuania ; 

 Bath [formation] , (Siemiradzki) , 



7. tula, n. Like T. cadus, but degeneration, smoothness and 

 reduction of whorl — incipient serpenticone stage — sets in at about 

 85 mm. diameter ; body-chamber about ij whorl ; " Sherborne, Dorset," 

 [Milborne Wick, Somerset] ; Fullers' Earth Rock, (Milborne Beds) ; 

 S.B., ex Darell, Coll. 1263 ; Genotype and Holotype ; S. 56, 38, 93, 37 ? ; 

 80, 40, 73, 35 ; 98, 34-5, 49, 38-5 ; about ij whorl body-chamber, all 

 but complete. 



T. subcontracts, Morris & Lycett sp. Am. subcontract's, M. & L., 

 op. cit, p. 11 ; PI. 11., fig. 1 (pars), see above p. 43. A cadicone like 

 T. tula up to about 60 mm. diam., but with less strong ornament ; then 

 degeneration — smoothness and contraction. Test preserved, but worn ; 

 mouth-border also preserved — a plain band preceded by a ventral ridge 

 of low relief, and that is preceded by another still less strong ; between 

 the two presumably a thickening of test, making a constriction on cast, 

 which should be especially noticeable on lateral area. Minchinhampton, 

 Gloucestershire ; Great Oolite, Shelly Beds ; Geol. Surv. Engl., ex Lycett 

 Coll. 25610 ; Lectotype ; S. 49, 37, 80, 34 ; 86, 35, 51, 35 ; max. 90. 



TuLOPHORlTES, g. n. Genotype, T. tulotus, n. Somewhat of 

 Tulites stage in inner whorls, but umbilicus distinctly gradate, with edge 

 of umbilical wall well rounded off. Ribs on venter less strong, more 

 approximate, and less persistent than in Tulites. [S.l. with L2 somewhat 

 elaborate, broad, its longer part inside]. England. 



T. prseclarus, n. In shape like what would be expected between 

 Tulites cadus and T. tula, but with less development of ornament. 

 Indication of end of mouth with strong contraction on cast. Troll, 

 near Thornford, Dorset ; Fullers' Earth Rock, (Thomford Beds) ; S.B., 

 ex J.B., Coll. 1914 ; Holotype ; S. 82, 39, 87, 33 ; 137, 32, 50, 38 ; max. 140. 



T. tulotus, n. Somewhat like T. tula, but with a more contracted 

 and gradate umbilicus, and with less pronounced ornament. End- 

 portion of body-chamber partly preserved, showing deep constriction on 

 cast ; preceding, on ventral area, are about half-a-dozen distant, broad 

 ribs of low relief, gradually increasing in strength — the last before 

 constriction being fairly strong. Troll, near Thornford, Dorset ; Fullers' 

 Earth Rock (Thornford Beds (hard stone) ; S.B., ex J.B., Coll. 1920 ; 

 Genotype and Holotype ; S. 66, 42, 88, 27 ; no, 36, 51, 35 ; max. c. 118. 



M adarites, g. n. (Stephanoceras, Teloceras, Auctt.). Genotype, M. 

 madams, n. Cadicones passing towards serpenticones. Slight sign of 

 Tulites stage in inner whorls of genotype up to about 45 mm. diam. ; 

 some undulation of upper edge of inner margin for about another half- 

 whorl indicates attempt to continue Tulites stage. Except for this, 

 after about 45 mm. diam., long before cadicone stage is complete, pro- 

 nounced smoothness is established. [Anamorphs should show more 

 distinct Tulites stage]. Umbilicus deep, contracted, funnel-shaped, 

 with deep walls nearly superimposed in cadicone stage. S.l. simple, 

 Li broad, not quite so long as EL ; L2 expanded, longest part towards
