MoLLUSCA IN THE MaYA LoWLANDS 



TIKAL: 3 unmodified, 4 pierced for suspension 

 (M, p. 67, "Marginella, probably all apicina 

 Menke"; however, as she cites Proskouriakoff's 

 photo, above, and Kidder's photo, below, it is most 

 probably this subspecies). 



UAXACTUN: Ricketsons list 64 unworked 

 "Marginella apicina" in two cists, 2 perforated 

 in another (RR, pp. 199-200, pi. 6^,d). Kidder 

 lists 185 in two Tepeu caches, all pierced (106 in 

 jar with snake vertebrae and i Olivella; K, pp. 

 61—62, fig. 82,6). As at Mayapan, above, it is 

 clear from Kidder's illustration that these shells 

 are half the size of apicinum apicinum Menke or 

 less, and are probably this subspecies. 



Comment: This tiny shell was apparently not con- 

 sidered worth drilling for perforation. In all pierced 

 examples at Dzibilchaltun, the hole was broken, 

 not drilled. Kidder mentions the same at Uaxactun; 

 this seems to be true also at Mayapan. 



Prunum guttatum (Dillwyn) 



Illustration: Plate 12,^. 



Modern distribution: Common on all three coasts 

 from Turneffe Islands, B.H., to Chencan, Cam- 

 peche and on the offshore atolls. 



Archaeological occurrence: 



ISLA CANCUN MIDDEN: 4 unworked, For- 

 mative. 



Prunum labiatum (Valenciennes) 



Illustration: Plate 12,/. 



Modern distribution: Moderately common on all 

 three coasts, Isla Cozumel, Q.R., to Isla Carmen, 

 Camp. Also the offshore atolls. 



Archaeological occurrence: 



DZIBILCHALTUN: 46 unworked, Formative; 

 I with drilled hole near rim. Formative; 4 un- 

 worked, probably Formative; i unworked. Late 

 Early period; i tinkler, spire removed, sawed per- 

 foration at base. Late Early period or Pure Flores- 

 cent; i unworked, Pure Florescent. 

 MAYAPAN: 8, all but one perforated, probably 

 Decadent period (P, p. 386, fig. 44,1:, as "Margi- 

 nella labiata"). 

 CHICHEN ITZA: i perforated (P, p. 422, fig. 



TIKAL: I unworked, not dated; 5 perforated, 

 four of these Formative (Chuen), one probably 

 Late Classic (M-MS). 



Prunum, cf. storeria (Couthouy) 

 Illustration: Couthouy, 1837, pi. 9, figs. 1,2. 

 Modern distribution: Not collected on peninsula. 

 Archaeological occurrence: 

 TIKAL: 2 unworked, not dated (M-MS). 



Comment: Marginellas, in general, are exceedingly 

 common in Formative deposits in Yucatan as un- 

 altered specimens. Later they occur less commonly, 

 usually perforated for use as beads (see Table 2). 



Family: CONIDAE (cones) 



Conus floridanus Gabb

 with spire cut off (unfinished tinkler.?). Forma- 

 tive; I unworked, Pure Florescent.
