(DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] Valvulina oviedoiana d'Orbigny, 
Triloculina bassensis Parr and Bolivinita rhomboidalis (Millet) from Florida Bay and 
environs are described and discussed. Specimens of Valvulina oviedoiana lacking the 
valvular tooth are quantitatively compared with those with valvular tooth and are 
presently considered to represent the same species. Triloculina bassensis from Florida 
Bay is compared and considered conspecific with specimens of Millolina angularis Flint. 
Triloculina bassensis from Australia and Triloculina cf. T. bassensis from Bikini. 
Triloculina bassensis Parr is considered to be the valid name of the species at the 
present time. A specimen previously listed as Bolivina sp. from Florida Bay is identified 
as Bolivinita rhomboidalis (Millet).

A recently metamorphosed population of the nine-armed tropical sea star, Luidia 
senegalensis, was found on the southwest coast of Florida in November 1965, and 
growth was followed for 16 weeks. An analysis of stomach contents was made. It 
showed the bivalved mollusk, Abra aequalis to be the dominant food source. The growth 
rate of L. senegalensis was considerably more rapid than the growth rates of those 
temperate species of sea stars that have been studied.

The shallow waters of Florida Bay and the Florida Keys are important nursery grounds 
for pink shrimp of the Tortugas grounds. Since 1965, biological observations on 
postlarval and early juvenile pink shrimp were made in these extensive estuaries. 
Postlarvae were sampled quantitatively once each month on incoming night tides at 
Whale Harbor Bridge near Islamorada (upper Florida Keys). As part of a cooperative 
plan similar observations were taken at three additional sites in the lower Keys by 
biologists of the Florita State Board of Conservation. This work established that large 
numbers of postlarval shrimp enter Florida Bay from the Atlantic Ocean and that 
recruitment continues throughout the year. Most postlarvae pass through the Keys into 
Florida Bay in late spring, summers and early fall. We expanded the sampling of 
juvenile shrimp in 1967. Quantitative samples have been taken monthly with a modified 
marsh net at 22 widely distributed shallow-water sites. Earlier samples were taken 
with the unit-area suction sampler designed by personnel at this station. Examination of 
samples from Florida Bay revealed that early juveniles increase in abundance during 
the summer and become most numerous during the fall. This concurs with the 
observation that postlarvae enter Florida Bay before and during these seasons. The data 
we have collected on incoming postlarvae and early juveniles indicate that the 
distribution of early juvenile pink shrink in Florida Bay depends primarily on the degree 
of postlarval penetration. Maximum concentrations of early juveniles occur in the 
western and southern portions of the Bay, generally in areas that receive large 
volumes of waterflow from the Gulf of Mexico and the Atlantic Ocean - a demonstrated 
source of postlarvae. Conversely, northeastern Florida Bay, which receives little 
waterflow from these sources, contains few early juveniles. At three stations in the 
northeastern Bay, we collected no pink shrimp during the first 6 months of sampling. 
The western and southern portions of the Bay are characterized by more stable 
salinities and temperatures, lower turbidities, and more extensive seagrass beds than
