  • Author's Response
    Dear Authors, I carefully read your responses to the reviewer’s comments and your revised manuscript. You addressed most of the reviewer’s comments and you improved the manuscript. Thank you. However, there are a few points that I would like to you to work on. Most of them are related to open questions of the reviewers in their comments. While you answer very well to these questions in your point to point response, too often, you do not include that information in the text of your manuscript. I think you should include such information because, if the reviewer asked that question, it is most probably because the information was missing or should be clarified in the manuscript. Here is the list of things I would like you to consider in a revised version of your manuscript. Response: Thank you for your comment. We integrated the requested changes in the manuscript, and provide a second markup version. • I suggest that you add the explanation provided to Lazarus comment’s about the glue somewhere in the text, maybe in section 2.3 Response: A paragraph about this was added in second 2.2 when discussing about the choice of the glue, on lines 166 to 169. • I also suggest to add on line 286 : “(…) and to send any suggestion to improve the taxonomical framework of the database” or something similar. Response: This was added as suggested on lines 301 to 302. • I suggest you add something in the discussion about the usefulness of improving the identification to a level that is useful for paleoenvironmental research.

  • Reproductive and Nutritional Cycles of the Crab <Emphasis Type="Italic">
    REPRODUCTIVE AND NUTRITIONAL CYCLES OF THE CRAB PORTUNUS* PELAGICUS (LINNAEUS) (DECAPODA: BRACHYURA) OF THE MADRAS COAST BY A. ABDtm RAHAMAN (Department of Zoology, Madurai University,~ Madurai,-2, India) Received December 28, 1966 (Communicated by Prof S. Krishnaswamy, l~.A.sc.) ABSTRACT The gonadal and hepatic indices were deterrmned. Even though the crab Portunus pelagicus is a continuous breeder, there appears to be three maximal periods of development of the gonad and hepatopancreas. The gonad index is high in the months of November-January and June and the hepatic index shows the greatest development in the months of November-January and August. There appears to be a direct relationship between gonadal and hepatopancreatic development. These results have been discussed in the light of previous work. INTRODUCTION THE reproductive cycle of invertebrates and their sexual periodicities have been extensively studied by many workers (Bennett and Giese, I955; Farmanfarmaian et al., 1958; Giese, 1959 a, 1959 b; Giese et al., 1964; Raha- man, 1965). Of these mention may be made of the studies on the periodic changes in the reproductive cycle of several species of arthropods of tem- perate regions by Boolootian et al. (1959) and Giese (1959). Except for the work on the Indian prawn Penaeus indieus (Subrahmanyam, 1963) similar work on tropical arthropods has been very few. Prasad and Tampi (1953) studied the biology of the blue swimming crab, Portunus pelagieus (Neptunus pelagieus) which forms an important fishery along the east coast of India. Delsman and De Man (1925) found berried crabs of this species throughout the year in Batavia. Prasad and Tampi (loc.

One species of the dorippid crabs is described new, Dorippe? carpathicp. sp. n. The occurrence of the genera MacrophthaZmus and Dorippe supports closer affinities to the Recent tropical/subtropical Indo- -Pacific realm.

Baluk & Radwanski 1977) yrl:elded numerOllls remains of decapods, not only in the rich assemblages from the famous Korytnica Clays (see Forster 1979) but also from the sands and the detrital bryo­ zoan-algal Limestones of the Leithakalk type, which represent the more littoral zones of the basin. The majority (199 specimens) are fragments of fingers or chelae only, like the assemblage from the Korytnica Clays. The fauna contlains, however, also nine carapaces or internal moulds of carapaces (Table 1). The preservation of the investigated material is only moderately good, permitting at most; particularly the fragments of fingers, Jidenti­ fication toa generic or even higher taxonomic level. In spite of this jnconvenience, but considering the fact, that the assemblage is the first known decapod fauna from this area, the aim of this paper is to present the material and to discuss its taxonomic, ecological and biogeographical setting as far as possible.

Volume 122 1967 Number 3599 Porluiiid Crabs from the International Indian Ocean Expedition In the Smithsonian Collections (Crustacea: Portunidae) By W. Stephenson and May Rees^ The present material, mostly collected by the Anton Bruun on Cruises 1 and 4B, comprises 35 recognisable species that are present in very unequal numbers. Of the total of 3444 specimens, 2250 were of one species (Portunus argentatus). Of the remaining 1194, 442 specimens were of one species (Charybdis hoplite''i) and 550 of the other four {C. callianassa, C. edwardsi, C. rostrata, and P. pulchricnstatus) At the other extreme, 18 species were represented by less than five specimens. Several of these are common inshore or shallow water species in the Indo-West Pacific area, including Cfenatw^, C. natator, P. pelagicus, P. sanguinolentus, Scylla serrata, and Thalamita crenata. Their small numbers indicate merely that during the cruises these environments usually were neglected in preference for offshore situations. There is comparal)le heterogeneity in the numbers of species re- corded from the difl'erent stations; thus, five species were recorded from 1 station (202A), four species from 7 stations, three from 10, two from 16, and one species from 34 stations.

Seven males and three ovigerous females were captured in July 2019. Key mor- phological features and internal structures are described, with particular attention to the chelae, mandibles, gills, cephalothoracic and abdominal sculpturing, and gastric mills. The red-and-white coloration is described and illustrated from fresh specimens. The geographic range, depth of occurrence, stomach contents, and fecundity of the species are also noted.
