MoLLUSCA IN THE MaYA LoWLANDS 



olaria distans Lam." with two perforations for 

 suspension, in Chultun 3 (RR, pp. 199-200, prob- 

 ably repeated in K, p. 61). This may be F. hunteria 

 (see comment below). 



Comment: Regarding confusion of F. hunteria and 

 related forms, see HoUister, 1957. There is an origi- 

 nal form, obtained from shrimp trawlers, for which 

 he opts the F. lilium (F. v. Waldheim), and a later- 

 named Florida species which has been called F. 

 hunteria (Perry). A third, also obviously closely 

 related form, taken by shrimp trawlers off Cam- 

 peche, is F. branhamae Rehder and Abbott. Oddly, 

 our specimens from the peninsula are clearly the 

 Florida species, hunteria, including those from 

 Campeche which were all collected in or near shal- 

 low water. F. distans Lamarck is a later synonym 

 for F. lilium, not hunteria. 



Fasciolaria tulipa (Linne) 



Illustration: Plates io,^,<^(/; Tib. 



Modern distribution: Common on all three coasts, 

 from Turneffe Islands, B.H., to Isla Carmen, 

 Camp. Also offshore atolls. 



Archaeological occurrence: 



DZIBILCHALTUN: 37 unworked, mostly For- 

 mative; I may have been drilled for suspension, 

 but this may have been natural (see Table 2). 

 MAYAPAN: i unworked, probably Decadent 

 period (P, p. 387, f^g. 47,z). 

 ISLA CANCUN MIDDEN: 478 unworked. 

 Formative. 



Pleuroploca gigantea (Kiener) 



Illustration: Plate ii,£^. 



Modern distribution: Rare on east coast, collected 

 from Corker Cay, B.H. Common on north and 

 west coasts from Isla Holbox, Q.R., to Isla Car- 

 men. Alacran Reef. 



Archaeological occurrence: 



DZIBILCHALTUN: 25 unworked and 4 cut, 

 preparatory to some use as jewelry. Formative 

 through Pure Florescent (see Table 2). 

 MAYAPAN: i, spire removed, Proskouriakoff 

 suggests may have been used as trumpet (P, p. 

 384, fig. 47,^, as "Fasciolaria gigantea" which is 

 this species), i unworked (P, p. 387, listed as 

 "Fasciolaria papulosa", which may have been this 

 species; cf. Abbott, 1954, p. 242); both probably 

 Decadent period. 



CHICHEN ITZA: i juvenile specimen, un- 

 worked, illustrated (P, fig. 51, A) and correcdy 

 captioned as this species, not listed in text 

 (provenience of lot: "Chichen Itza and Balam 

 Canche"). Dr. J. Ladd (personal communication) 

 notes that two adult specimens were recovered 

 from the Sacred Well, one of which had its spire 

 cut off. 



ISLA CANCUN MIDDEN: 84 unworked, For- 

 mative. 



BARTON RAMIE: i unworked, in mixed debris 

 (W, pp. 526, 528, as Fasciolaria gigantea). 

 TIKAL: 34 unmodified, immature (M, p. 67; 

 period not yet determined); 3 cut fragments, one 

 Middle Formative (Chuen), one Early Classic, 

 one undated; 3 slightly altered, two of these Early 

 Classic, one undated (M-MS). 

 UAXACTUN: i with spire removed, which 

 Ricketsons suggest is trumpet; identification not 

 given, but from photograph (RR, pi. 69, r; K, p. 

 61, both as "Fasciolaria"), it is clearly this species. 



Latirus ceratus (Wood) 

 Illustration: Keen, 1958, fig. 603. 

 Modern distribution: Pacific. 

 Archaeological occurrence: 



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



Latirus infundibulum (Gmelin) 

 Illustration: Warmke and Abbott, 1961, pi. 2,/. 

 Modern distribution: Not collected on peninsula. 

 Archaeological occurrence: 



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



Family: TURBINELLIDAE (chank shell) 



Turbinella angulata (Solander) 



Illustration: Plate ii,e. 



Modern distribution: Common on all three coasts, 

 from Turneffe Islands, B.H., to Isla Carmen. Also 

 on offshore atolls. 



Archaeological occurrence: 



DZIBILCHALTUN: 24 unworked, mostly For- 

 mative (see Table 2); i with spire removed for 

 use as a trumpet, in Formative cache; 3 other 

 pieces of body whorl and columella partially cut 

 for use in manufacture. 



ISLA CANCUN MIDDEN: c)6 unworked, For- 

 mative. 



HOLMUL: 2, one with spire removed, one neatly 

 cut in half vertically with resultant edges finely
