DEVANEY AND BRUCE 



Pacific waters including the Marshall Islands (Chace, 1955). 

 Two crangonid shrimps were taken in the Enewetak 

 Lagoon. One is possibly a new species of Pontophilus, 

 whereas the other, I'ercoia gibbosa, was previously known 

 only from south Australia. 



PALINURA 



At least four palinuran lobsters are represented at 

 Enewetak. Panulirus penicillatus is a common inhabitant of 

 the windward reef flat and was recorded from Arno Atoll 

 in the southern Marshall Islands (Holthuis, 1953). This 

 spiny lobster was the focus of population and other life his- 

 tory studies at Enewetak during 1978 and 1979 (Ford et 

 al., 1979; Ebert and Ford, 1986). Juvenile (puerulus and 

 post-puerulus) stages of this wide-spread Indo-West Pacific 

 rock lobster have been recorded by Cooke and McDonald 

 (1981) from Enewetak. Three specimens of P. longipes 

 femoristriga were identified from a collection made in a 

 surge channel near the outer reef. Although not previously 

 reported from the Marshall Islands, this subspecies is 

 reported widely from Japan, the Moluccas, New Guinea, 

 eastern Australia and Polynesia (George and Holthuis, 

 1965). Panulirus versicolor, recorded by Holthuis (1953) 

 from Arno, has not been reported at Enewetak. Parribacus 

 antarcticus and Palinurellus wieneckii are now known from 

 Enewetak. Although each of the last two species has a 

 broad Indo-West Pacific distribution, only P. antarcticus 

 had previously been recorded from the Marshall Islands 

 (Arno) by Holthuis (op. cit.). The latter has also been 

 recognized in waters off Kwajelein Atoll (S. Johnson, per- 

 sonal communication). 



COLLECTION RECORDS 



Taxa are listed in the same order as in the checklist 

 under their respective families. Higher categories may be 

 found in the checklist. These records are not known to 

 have been previously published. When known, the islet, 

 month, year, habitat, depth, collector, identifier, and 

 number of specimens are given. Many of the specimens 

 collected between 1956 and 1971 and determined by 

 L. B. Holthuis (LBH) are deposited at the Allan Hancock 

 Foundation. Other specimens have been deposited in 

 several institutions, mainly MPRL, BPBM (Honolulu), 

 RMNH (Leiden), and USNM. Identifiers AJB and DMD 

 refer to the authors; other identifiers are named in full.
