NO. I FORAMINIFERA IN LONG ISLAND SOUND BUZAS 55 



Living and dead individuals belonging to this species occur with 

 low frequencies throughout L.I.S. This species is not, however, 

 found at depths of less than 13 m. Parker (1952b) suggested that 

 R. dentaliniformis may be confined to sediments containing mud. 

 The present study substantiates her suggestion somewhat. R. denta- 

 liniformis is often found in the offshore stations which are usually 

 muds. It was not found, however, at stations 125 and 80, which are 

 offshore sands. As mentioned above, this species is conspicuously 

 absent from all shallow stations including those whose particle-size 

 distribution is similar to the offshore muds.

Living and dead individuals of this species are found in L.I.S., 

 but their occurrence is scattered and never comprises more than 2 

 percent of the total fauna.

A few specimens that probably belong to this species, which was 

 described by Parker (1952b, p. 444, pi. 1, figs. 24, 25), were found 

 at station 98a in Lloyd's Harbor at a depth of 4 m. None of the 

 specimens was living at the time of collection, and no complete 

 individuals were observed. Most of the specimens were so fragile 

 that they disintegrated when the sample was dried.

This species is found throughout L.I.S., but has its greatest abun- 

 dance in the central areas of the traverses. In the central areas the
