P. (^LainelUconchci) circinata of tlie Atlantic can hardly be separated 

 from P. alternata of the Pacific ; Cylherea magdalenae Dall is the 

 analogue of C. slrigellinn Dall, of the Atlantic fauna; C. rigida 

 Dillw. is found on both shores; C. mtdticostaia Sowb. is allied to 

 C. Hsteri ; Chione, suhroslrata lives on both coasts; forms of C. icn- 

 datella ohew resemble C. cancellata; C purpurissata T)i\\\ is elosely 

 related to C. puher Val.; C. pidicaria is the analogue of C. intapur- 

 purea of the Atlantii- Jauna; while C. obliterata Dall "is the an- 

 alogue of C. latilirata Conr., and C. marise Orb. of C. paphia L." —

 1902. In this interesting paj^er the author records about 70 species, 

 and a number of varieties including several which are described as 

 new. The following is a brief review of the new forms : 



Cyi'RAEA ARGi'S var. minor, apjilied to specimens under 55 mm. 

 in length. 



C. ARGUS var. concatenata, shells with numerous small ocellated 

 spots disposed in small chains, which cross each otiier more or less

 violet ring more or less apparent. 



C. TALPA var. saturata. In this variety the three dorsal bands

C. TABESCENS. C. raskleighana^ C. alveolus, and C. elaiodes are 

 all considered varieties of C. tabescens. 



C. CAURICA var. PALLIDA. This has the form of var. obscura 

 Rossiter. but tending to albinism, while var. obscura tend- to

C. ARABICA var. ATRA. Tinted witii Mack over the entire dorsal 

 surface. This var. corresponds to the var. nigricans of (A eglatina. 



C. EGLATINA var. PALLIDA. Based on two shells with very 

 marked tendencies to albinism. 



C. niSTRio var. luctuosa. This presents exactly the same ex-
