Popis:	Patterns of seasonal change in the abundances of the planktonic larvae of four sympatric hermit crabs were examined at five fixed stations over 18 months in Christmas Bay, Texas. Clibanarius vittatus (Bosc) was present in the plankton from April through October, Pagurus longicarpus Say from September through May and P. pollicaris Say from December through February. Pagurus annulipes (Stimpson) zoeae were the most frequently encountered zoeae and were found throughout the year, but were most abundant in late spring and summer. Zoea I of P. annulipes and P. pollicaris were found to be reliably distinguishable on the basis of their carapace lengths. Clibanarius zoea I were very abundant (3149) and 42 megalopa but no zoea II–V were found. Inadequate sampling and the short durations of these missing stages do not seem sufficient to explain their absence.
