This race, which Pfeiffer says Wright found under decaying leaves 

 at "Vignales," has so far not been rediscovered by any subsequent 

 collectors. It is abundantly represented in many collections but al- 

 ways dating back to Wright's collecting. 



The shells are usually dark red, though at times paler individuals are 

 present. Spiral color bands if present are scarcely noticeable. The 

 shells are larger than those of the next subspecies. 



The specimen figured, U.S.N.M. no. 10970, one of four, has 5.3 

 whorls remaining, and measures : Length, 21.1 mm ; greater diameter, 

 12.8 mm ; lesser diameter, 8.3 mm. 



TURRITHYRA (TURRITHYRETES) ECHINULATA ECHINELLA, new subspecies 



Plate 14, Figure 10 



This race was collected in the Sierra del Abra, 6 miles west of 

 the River Cejanal in front of Enrique Veles's place, where it is found 

 on bushes. 



It is usually paler, with the spaces between the spiral cords darker 

 than the cords and their spines. It is smaller than typical T. {T.) 

 ech inulata ech inulata. 



The type, U.S.N.M. no. 468683, has 4.9 whorls remaining and meas- 

 ures: Length, 17.7 mm; greater diameter, 9.0 mm; lesser diameter, 

 7.2 mm. 



TURRITHYRA (TURRITHYRETES) SINUOSA (Wright) Pfeiffer 



Shell elongate-turreted, varying in color from white through pale 

 yellow, through buff to reddish in ground color, unicolor or inter- 

 ruptedly spirally banded; peristome white or pale yellowish buff. 

 Nuclear whorls about 2, inflated and strongly rounded, smooth except 

 the last part of the last turn, which shows a few incremental lines. 

 Postnuclear whorls also inflated and strongly rounded, separated by 

 a well-constricted suture and marked by fairly regularly developed 

 and spaced, retractively slanting, threadlike axial riblets crossed by
