SHBLL-COLLECTING ON THE MOSQUITO COAST OF NICABAGTJA— II. 



BT W. H. FLUCK. 



I wish to acknowledge my indebtedness to several naturalists who 

 have helped me in naming and verifying my shells, especially Messrs. 

 Pilsbry, Johnson, Dall, Schick, Shackleford, Hodgson and Ancey. 

 Without their generous help a solitary student like myself would 

 be like the old woman who lived in the shoe, with one difference, 

 trouble about shells, not children. 



The localities mentioned in this and in subsequent papers may be 

 found by referring to my map, page 9 of this volume. The names 

 are somewhat blurred owing to rough paper and the reduction of the 

 drawing, but it answers the principal reason for its publication, the 

 location of Wounta Haulover, Wounta, Walfa Siksa, the Keys and 

 Wani. 

 Spirula peronii Lam. 



Wounta Haulover, and everywhere along the coast. No living 

 specimens were found, but perfect shells of this cephalopod, immacu- 

 late and beautiful, were taken in quantity. I nearly always found it 

 on the upper reaches of the beach among the dead algae and trash 

 cast up by the sea. 

 Murex brevifrons Lam. 



Wounta Haulover. A specimen is found now and again on the 

 beach, but the shell is not plentiful. 

 Murex bellus Rve. 



Same locality. One dead but perfect shell. 

 Sistrum nodulosum C. B. Ads. 



King's Keys. One shell. 

 Purpura trinitatensis Guppy. 



Man of War Keys. 

 Cymatium pileare Lam. 



Walfa Siksa. On the rocks and sand reaches at this place there 

 is good collecting, especially for bivalves. 

 Purpura floridana Con. 



This is the shell known as P. hsemastoma L., \ar.Jloridana Con. 

 Dr. Dall considers floridana of specific value. My shells are very 

 variable in form and marking. Some are smooth-whorled and the 

 color of beach sand; others are studded with one or two rows of
