221 THE DATES OF PUBLICATION OF CRUSTACEANA VOLS. 1-50 AND SUPPL. 1-10 BY L. B. HOLTHUIS Rijksmuseum van Natuurlijke Historie, Leiden, Netherlands Now that 50 volumes of Crustaceana have been published it seems a fitting occasion to give a list of the dates of publication of the various parts and of the supplements. The actual dates in some cases are different from those printed on the covers, although in only a very few cases this discrepancy is serious. I am most indebted to Mr. P. A. Kranenburg of Messrs. E. J. Brill for providing me with these data, viz., the data that the copies were sent out. The data of supplements 1 to 3 incl. and 5 could not be found in the files of Brill's; the ones given here are those on which the copies were received by the library of the Rijksmuseum van Natuurlijke Historie, they are at the most 1 or 2 days later than the actual dates of publication.

OCCURRENCE OF UCA (DELTUCA) URVILLEI (H. MILNE EDWARDS, 1852) IN THE SAUDI RED SEA (DECAPODA, OCYPODIDAE) BY P. J. HOGARTH Department of Biology, University of York, Heslington, York Y01 5DD, U.K. To date, three species of fiddler crab genus Uca have been recorded from the Red Sea: Uca (Thalassuca) tetragonon (Herbst, 1790), U. (Celuca) lactea albimana (Kossmann, 1877) and U. (Amphiuca) inversa inversa (Hoffmann, 1874) (see Lewinsohn, 1979). In the course of a recent survey of the southern Red Sea coast, a number of specimens of a fourth species, Uca (Deltuca) urvillei (H. Milne Edwards, 1852) were collected, during October 1984, at the following locations: 1) Shi'b Abu Al Liqa, 17°27'08"N 42°17'16"E: 1 a, 1 9, 1 juvenile; 2) Sawarmah, 16°40' 13 "N 42°43'41 "E: 2 3) Oreste Point, 1 6 ° 2 3 ' 1 1 "N 42°46'08"E: 2 2 99. .
