I7S 



The question of the subdivisions of the genus Tellina is highly involved, and in spite 

 of the valuable works of Bertin and Dall needs revision. 



The genus Tellina of Ltnnaeus was a heterogenous group, and for an account of the 

 opinions of différent vvorkers as to its Hmits référence may be made to Dall's useful summary 

 in his second work, cited above. In the follovving account the genus Tellina and subgenus 

 Tellina s. s., are adopted as restricted by Dall, and the same authors synonymy of thèse 

 groups is accepted as correct. Dall is, however, wrong in suggesting that T. virgata Linn. is 

 the type of the genus, for Children ^) designated T. radiata Linn. as the génotype in 18X2. 



The other subgenera represented in the collection are Arcopagia Leach -) — type Tellina 

 (Arcopagià) crassa (Pennant), Pseiidarcopagia Bertin ') — type Tellina {F sejidarcopagia) decîissata 

 Lam., Phylloda Schumacher*) — type Tellina [Phylloda) foliacea Linn., Anguhis Megerle °) — 

 type Tellina [Angidus) laticeolata (Linn.), and Peronidia Dall ") — type Tellina [Peronidia] 

 albicans Gmelin.
