CUBAN ANNULiAEIIDAE — TORRE AND BARTSiCH 271 



TUDOKA (AGUAYOTUDORA) RECTA MARTIENSIS. new subspecies 



Plate 26, Figure 1 



This subspecies was collected by Dr. Rodriguez at Finca San Carlos, 

 near the town of Marti, Camagiiey Province. It resembles the typical 

 race, but differs markedly from this by its much more uniform de- 

 velopment of ribs and much greater number of auricles at the summit 

 of the whorls. The nodulation of the axial ribs here is also much 

 more pronounced. 



The type, U.S.N. M. No. 493446, has 5.5 whorls and measures: 

 Length, 10.2 mm. ; greater diameter, 5.7 mm. ; lesser diameter, 5.0 mm. 



TUDORA (AGUAYOTUDORA) RECTA BARRETI, new subspecies 



Plate 26, Figure 2 



This subspecies comes from Maragudn, Rio Hondo, about 13 miles 

 southeast of Camagiiey, Camagiiey Province. It differs from the 

 other two races in being much larger, with the axial ribs much more 

 distantly spaced, and with the auricles at the summit strongly devel- 

 oped, in which respect it resembles T. {A.) recta martiensis. 



The type, U.S.N.M. No. 493444, has lost the early whorls. The 

 4.2 turns remaining measure: Length, 12.7 mm.; greater diameter, 

 7.5 mm.; lesser diameter, 6.2 mm.

vol. 58, p. 76. 



The typical subspecies was collected by Gundlach between Las Tunas 

 and Puerto Principe, Camagiiey Provmce. It resembles most nearly 

 T. {A.) recta martiensis, from which it is easily distinguished, how- 

 ever, by the fact that the differentiation into the stronger and weaker 

 elements of the axial ribs is much more pronounced; the axial ribs 

 therefore are much more irregular ; also the auricles at the summit are 

 much less frequently developed than in T. (A.) recta martiensis. 



The specimen described and figured, U.S.N.M. No. 356367, a 

 cotype, has 6 whorls and measures: Length, 10.2 mm.; greater diam- 

 eter, 6.0 mm.; lesser diameter, 4.8 mm.
