176 EUGLANDINA. 



edge of the forms; their value can hardly be overestimated. 

 Crosse and Fischer 'and von Martens have contributed indis- 

 pensable material of great value, yet from the standpoint 

 reached by Strebel, it must be admitted that all other authors 

 have treated the subject in a comparatively superficial man- 

 ner. Since most of the species were included by Mr. Try on 

 in Vol. I of this work, I have restricted the following account 

 to strictly supplementary matter. 



I. TYPICAL FORMS OF EUGLANDINA. 

 South American Species. 



1. E. STRIATA (Miiller). Vol. I, p. 32. 



In his latest treatment of this species (Biologia Centrali 

 Americana, p. 79) Prof, von Martens includes as synonyms 

 Glandina strigosa Marts, (vol. I, p. 33) and G. lineata Strebel 

 (I, p. 32). It extends from southern Brazil to Colombia and 

 Guiana, but is probably not homogeneous over so wide and 

 varied a range, the examples before me showing considerable 

 diversity. 



2. E. FLOCCATA (Da Costa). PL 20, fig. 10. 



Shell fusiform with long spire, thin, ventricose ; pellucid- 

 brownish with remote chestnut streaks, and sparsely flecked 

 with rather indistinct whitish spots. Whorls 8, longitudinally 

 very closely plicate-striate, at the suture finely and very 

 closely crenulate. Columella arcuate, conspicuously truncate. 

 Aperture rather ample, brownish-white. Length 89, diam. 

 35, aperture 46x18 mm. (Da Costa). 



Colombia: La Armenia, near Bogota. 



Glandina floccata DA COSTA, Proc. Malac. Soc. Lond., iv, p. 

 66, pi. 7, f. 3 ( August 1, 1900). 



* * This fine species bears a strong resemblance to G. striata 

 Mull ; the last whorl, however, is rather more ventricose, and 

 exhibits a feature never found in that species, viz., the presence 

 of several white flecks scattered irregularly over the body- 

 whorl : the only other instance of similar spotting may be 

 observed in examples of G. vanuxemensis Lea, from Mexico" 

 (Da Costa).
