INTRODUCTION Stomtopods or mntis shrimps re inhitnts of littorl regions where they live in ottom revies or urrows. They re osionily ught in fish nets nd re lnded with the trsh t fish hrours. The lrve re pln..ltoni. Most spets of the generl iology of speies ouring on our ost re hrdly understood exept tht some speies re undnt nd omprtively ommon nd their mt~ril might e olleted redily for vriety of studies. The inost importnt is or might e their use s food for humn onsumption. A preliminry study ws Undertken y Tirmizi nd Bshir (1975) when individuls of mntis shrimps nd peneid shrimps of the sme size were studied nd oserved tht the edile met in the two ws of the sme weight. T.he speies omposition in the northern Arin Se shows diversifition. The erliest reords of Stomtopod in the northern Arin Se re in Wood-Mson (1895) of Squill supplex from Bomy. Out of the 37 speies reported from the Arin Se out 28 speies re known from long the Indin suontinent (Mnning, 1988). Big (1954) for the first time fter prtition from Krhi, Pkistn reord~d 3 speies nd then Tirmizi nd Mnning (1968) from Pkistn in monogrphi work reportedl7 speies nd lter on Tirinizi nd Kzmi (198i) keyed out 19 speies. Ahmed et!. (1972) pulished list for mrine fun of Pkistn. This list inludes 8 speies of stointopods. Llyod (1908) mentions of Squill speies from southwest ost of Ari olleted y RIMSS Investigtor in 1907 nd himself reported 6 speies from Bomy nd Krhi~ Of these, the reord of Squill ov to ri (misspelled for rtori) is onsidered here to e mistkenly given from Bomy y Lloyd sine S. rtori ertinly does not our south or west of Vietnm (RBM). Chopr (193 9) fro. n South Arin ost reported Lysiosquill sewelli,.gonodtylus demni vr. espinosus, G. demni vr.? espinosus, Eurysquill sewelli nd from Kuri Muri Islnd Pseudosquill ilit. The gonodtylid lot tully ontined G. hopri Mnning, 1967 rid G. inipiens Lnhester, 1903 (Mnning, 1990). From

126 Pkistn Journl of Mrine Sienes, Vol.3(2), 1994 southern Omn Hogrth (1989) reported 3 speies. The fun of Somli ost is the lest known, only 3 species hve een reported from there (Mnning, 1988). Duris (1987) reported Ehinosquill guerinii from the western Indin Oen (Sootr Islnd). Ghosh (1990) mentioned 13 speies from Lkshdweep, only 4 of these fll in the re studied. All these speies re now inluded in the present key. In the key, tx ouring in the Pkistn wters re preeded y n sterisk(*). For nomenlturl hnges Mnning's works re generlly followed. Further, sed on Mnning's works of 1988 nd 1991 list is prepred for the speies ouring in the Gulfs nd the Red Se; these speies re not given in the key nd re listed elow: Fmily Coronidide: Neooronid trhurus (von Mrtens, 1881) Fmily Lysiosquillide: Lysiosquill mhult (Friius, 1793) Fmily Nnnosquillide: A9nthosquill derijrdi Mnning, 1970 Anthosquill viin (Noili, 1904) Keppelius hestriotelson (Brnrd, 1958) Pullosquill thomssini Mnning, 1978 Fmily ~urysquillide: Mnningi ri Mnning, 1990 Fmily Gonodtylide: Gonodtylus utirostris de Mn, 1898 Gonodty{us muttus Lnhester, 1903 Fmily Protosquillide: Chorisquill spinosissim (Pfeffer, 1888) Fmily Pseudosquillide: Pseudosquill meglophthlm Bigelow, 1893 Fmily Squillide: Alim neptuni (Linneus, 1768) Anhisquillfsit (de Hn, 1844) Crinosquill rint (Serene, 1950) Clrid f/lx (Bouvier, 1914) Kempin stridulns (Wood-Mson, 1895) Kempin mikdo (Kemp nd Chopr, 1921) Lenisquill gilesi (Kemp, 1911) Lenisquill lt (Brooks, 1886) Leptosquill shmeltzii (A.
