The identification of late Bathonian beds and the position of the boundary between the Bathonian and Callovian in Kutch, western India, continued to be elusive until recently. The dominant ammonite faunas show strong endemism and thus are of little value in worldwide age correlations. The present paper records Epistrenoceras Bentz from the Patcham Formation of Jumara, which is regarded as a biological stopwatch indicating only the upper Bathonian. This find, together with other recently recorded time-diagnostic forms, now resolves the uncertainties.

AbstractSystematic descriptions of specimens collected from Pachchham ‘Island’, Kachchh, Western India, belonging to the genera Micromphalites Buckman and Gracilisphinctes Buckman are given. Their affinities with the different forms belonging to the above genera are discussed and described as Micromphalites aff. hourcqui Collignon and Gracilisphinctes cf. arkelli Collignon respectively. The distribution of these two genera in other regions is also briefly discussed.

Range Of Variation

Epistreptophyllum cornutiformis Gregory, 1900, is the name assigned to a Middle Jurassic population of scleractinian corals from Kachchh, western India. Measurements of ten variables from 84 specimens of this population have been statistically examined by means of univariate and multivariate analyses. A wide range of variation in corallum shape, septal perforation, lateral septal surface ornamentation, nature of the endotheca, and that of the columella is observed. The great majority of specimens are solitary. The wide range of gradational variation observed in this population corresponds to and includes the morphological characters described for various scleractinian genera such as Protethmos Gregory, Metethmos Gregory, Frechia Gregory, and Epistreptophyllum Milaschewitsch. The assignment of these genera to this later senior synonym genus is supported by the description of a well-preserved topotype from Nattheim. The ornamentation of the septa in Epistreptophyllum is detailed and distances it from typical pennular corals.

Abstract The present paper deals with the infestation of freshwater fishes Labeo boggut, Oreochromis niloticus, Systomus sarana, and Xenentodon cancila by the parasitic isopods Alitropus typus and Tachaea spongillicola in Tapti, a westward freshwater flowing river of India. It is the first record of the infestation of parasitic isopods Alitropus typus, and Tachaea spongillicola in the freshwater fishes of river Tapti with new hosts’ species Labeo boggut, Oreochromis niloticus, and Systomus sarana.

New collections of Macrocephalitinae from the ?Upper Bathonian – Lower Callovian of Kachchh (Cutch olim) make it possible to discern six successive taxonomically distinguishable faunal associations. These are, from above, (6) M. semilaevis association, (5) M. formosus association, (4) M. dimerus association, (3) M. elephantinus association, (2) M. madagascariensis association, (1) M. triangularis association.Of these, Nos. 1, 4, and 6 formed the bases of the M. triangularis, M. dimerus, and M. semilaevis biozones respectively. The majority of the 19 nominal species and 6 genera in the literature on Kachchh may be condensed into only 6 dimorphic species of undivided Macrocephalites.
