LIST OF STARFISHES' 

 Determined by John I. Northrop 



Linckia Guildingii Gr. Collected at [Nassau and also on Andros. 



Echinaster lentus ? Nassau. 



Ophiocoma echinata Ag. Common in pools and under stones at 

 low water. 



Ophiocoma pumila Liitken. Nassau. Twenty-one specimens. In 

 one the upper arm-spines are flattened vertically, and the tip is 

 indented or sometimes toothed. A few spines are much 

 broader at base and prolonged backward in a point over the 

 upper arm-plates, making them appear arrow-shaped. 



Ophiocoma Riisei Liitken. One specimen from near Nassau. 



Ophiura brevicauda Lyman. One specimen from near Nassau, 

 under stones. 



Ophiura cinerea Lyman. Nassau. The seventh joint of arm has 

 ten spines instead of eight. 



Ophiura appressa Say. Nassau. Four specimens. 



Ophiomyxa flaccida Liitken. Nassau. Single specimen from near 

 Quarantine Station. 



Ophiothrix (Erstedii Lutken. One specimen. Lyman states that 

 this is the most abundant species of Florida and the West 

 Indies. It did not seem to be at all common in the Bahamas. 



Ophiothrix Suensonii Lutken ? Five specimens found on sponges in 

 the sea-garden near Nassau, seem to have but three or four 

 spines. 



' Owing to their incompleteness the critical notes have been omitted.
