Dentalium (Graptacme) cborcum Conrad 

 Dentalium eboreum Conrad 1846, Proc. Acad. Nat. Sci. Philadelphia 3, p M : HhNr>tRS<jN 1920. 

 Bull. U.S. Nat. Mus. No. Ill, p. 66, pi. 10, figs. 3-5, 8-9; pi. II. fig. 6. 



Notes. This may be a very common species in some localities. It lives apparently 

 in fairly shallow water and down to depths of 80 to 100 fathoms. The shells being 

 solid and strong are often washed up on the beaches in considerable numbers. The 

 following data add to the distribution records of this species on the west coast of 

 Florida and extend the range to Mustang Island, Texas. 



Records. FLORIDA: Clearwater; Gulfport; Bradenton Beach. TEXAS: Mustang Island. 



Dentalium (Graptacme) semistriolatum Guilding 

 Dentalium semistriolatum Guilding 1834, Trans. Linn. Soc. London 17, pt. I . p. 34. pi. 3, figs. I -6; 

 Henderson 1920, Bull. U.S. Nat. Mus. No. Ill, p. 69, pi. 11, figs. 1-3, 8-9. 



Notes. Several additional records of this rather common West Indian species are 

 added. The one from off Fort Walton, Florida, adds one more species to the list of 

 West Indian forms that are found in deeper water in the northern Gulf. The record 

 for Swan Island carries the distribution of the species well into the western Caribbean. 



Records. FLORIDA: 15-35 miles off Fort Walton in 13-19 fathoms (L. A. Blrrv). CUBA: 

 Pueblo Nuevo and Cardenas, Matanzas Bay, Matanzas. VIRGIN ISLANDS: Virgin Gorda. 

 HISPANIOLA: Monte Cristi, Santo Domingo; LESSER ANTILLES: Guadeloupe. [CARIBBEAN 

 ISLANDS: Swan Island in 60 fathoms. 



Dentalium (Graptacme) calamus Dall 

 Dentalium calamus Dall 1889, Bull. Mus. Comp. Zool. 18, p. 421 ; Henderson 1920, Bull. U.S. 

 Nat. Mus. No. Ill, p. 72, pi. 12, figs. 7-8. 



Notes. This is a rare but very characteristic species which is found in rather shallow 

 water. The two records from the Bahamas were collected by Owen Bryant. 



Records. BAHAMA ISLANDS: Whale Cay Channel, Great Abaco Island in 3 fathoms; Dick's 

 Point, Nassau, New Providence. 



Dentalium (Laevidentalium) callipeplum Dall 

 Dentalium callipeplum Dall 1889, Bull. Mus. Comp. Zool. 18, p. 419, pi. 27, fig. 12b; Henderson 

 1920, Bull U.S. Nat. Mus. No. Ill, p. 74, pi. 12, fig. 5. 



Notes. A very large, fine specimen of this rare species was collected by the Atlantis 

 in 2075 fathoms, which greatly extends the known depth for this species. 



Records. FLORIDA: 2h miles E.S.E. of Beacon D, Key Largo in 58 fathoms (L. A. Bi rrv). 

 CUBA: Atlantis, station 2964, Banco Paz, Las Villas (N. Lat. 20 56'; W. Long. 80^ 1 1 ) in 2075 

 fathoms. VIRGIN ISLANDS: St. Thomas (T. Bland). 



Dentalium (Laevidentalium) perlongum Dall 

 Dentalium perlongum Dall 1881, Bull. Mus. Comp. Zool. 9, p. 36; Dall 1889, Bull. Mus. Comp 

 Zool. 18, p. 419, pi. 27. fig. 6; Henderson, 1920, Bull. U.S. Nat. Mus. No. Ill, p. 75. pi. 9. fig. 1. 



Notes. Four fine lots, one of them with 8 specimens, were collected by the Atlantis. 

 The following are apparently the first Cuban records for this species. 



Records. Atlantis, station 2992B, off Bahia de Santa Clara, Matanzas (N. Lat. 23" 26 ; \N I ong 

 80° 28') in 535 fathoms; Atlantis, station 2993, off Bahia de Santa Clara (N. Lat. 23° 24 ; W. Long. 

 80° 44') in 580 fathoms; Atlantis, station 3345, off Banco Paz, Las Villas (N. Lat. 21 08'; W. Long. 

 79° 56' 30') in 700 fathoms; Atlantis, station 3370, off Puerto de Tanamo, Oricnte (N. Lat. 20 47'; 

 W. Long. 57° 1 1') in 450 fathoms.
