During the examination of an abnormal specimen of the Scottish Red Deer (Cervus elaphus) in the winter of 1930, my colleague, Mr. W. C. Miller, M.R.C.V.S., discovered several specimens of a bursate nematode lying on the connective tissue between the latissimus dorsi and the external intercostal muscles. Struck by the unusual habitat of such a worm, search was subsequently made in similar situations in other deer, and in two animals the same parasite was found.

In recent decades, major advances in the systematics of the Western Hemisphere genus Paracloeodes Day have been made in South America. Despite the taxonomic progress, uncertainties in identification remain due to the morphological similarities among some nymphs and due to the general lack of knowledge of the imago stages (only 4 of 20 are described from throughout the range of the genus). This study addresses these impediments in part through description of the male imagoes of six species (P. atroari Nieto & Salles, P. binodulus Lugo-Ortiz & McCafferty, P. ibicui Lugo-Ortiz & McCafferty, P. pacawara Nieto & Salles, P. peri Nieto & Salles, P. waimiri Nieto & Salles), description of two new species based on morphologically distinct nymphs (P. aristotelesi sp. n. and P. carolinae sp. n.), description of one new species based on morphologically distinct nymph and male imago (P. prismatobranchus sp. n.); redescription of three species based on type material (P. ibicui Lugo-Ortiz & McCafferty, P. leptobranchus Lugo-Ortiz & McCafferty and P. eurybranchus Lugo-Ortiz & McCafferty); proposal of one new synonym based on morphological analyses of specimens from Bolivia, Brazil and Uruguay, including type specimens (P. pacawara = P. morellii Emmerich & Nieto); and the presentation of a new key to identify nymphs from South America to the species level.

AbstractThe type specimens of Synarthonia bicolor and S. stigmatidialis were examined, leading the authors to revise their descriptions as well as the generic description. Also, two new species of Synarthonia, viz. S. psoromica and S. sikkimensis are described from India. Synarthonia psoromica, collected from the Nilgiri Hills of Tamil Nadu, is characterized by immersed synascomata and the presence of psoromic acid. Synarthonia sikkimensis, collected from Sikkim-Himalaya, is characterized by the sorediate thallus with a rhizomorph-like prothallus. These distinguishing characters are observed for the first time in Synarthonia. After considering the protologue of the recently described S. sarcographoides, a comprehensive account of this genus is made. In addition, a world key to all known species of Synarthonia is provided.

Models of collective animal behaviour frequently make assumptions about the effects of neighbours on the behaviour of focal individuals, but these assumptions are rarely tested. One such set of assumptions is that the switch between active and inactive behaviour seen in herding animals is influenced by the activity of close neighbours, where neighbouring animals show a higher degree of behavioural synchrony than would be expected by chance. We tested this assumption by observing the simultaneous behaviour of paired individuals within a herd of red deer Cervus elaphus. Focal individuals were more synchronised with their two closest neighbours than with the third closest or randomly selected individuals from the herd. Our results suggest that the behaviour of individual deer is influenced by immediate neighbours. Even if we assume that there are no social relationships between individuals, this suggests that the assumptions made in models about the influence of neighbours may be appropriate.

Thirteen centiped species and one symphylan are reported from the Galápagos Islands. Hanseniella caldaria (Hansen) is the first symphylan reported from the Galápagos Islands. Among the centipeds, Hemiscolopendra galapagosa Chamberlin is a new synonym of Scolopendra galapagoensis Bollman and should be deleted from the Galápagos list. Cormocephalus andinus Kraepelin, its probable junior synonym C. carolus Chamberlin, and Nannopodellus purpurascens Chamberlin, previously reported from the Galápagos Islands, were not in any collections made from 1974 to the present and may be extinct on the islands. Lamyctes coeculus (Brölemann), Lamyctes fulvicornis Meinert, and Newportia monticola Pocock are new records, and first appear in collections made in 1974. Two new species, Pectiniunguis krausi and Pachymerium perdrai, are described. The former had been misidentified previously as Pectiniunguis albermarlensis Chamberlin. While Pectiniunguis albemarlensis and Scolopendra galapagoensis may be Galápagos endemics, lack of knowledge about the centiped fauna of source areas precludes definitive statements.

Remodelling of cancellous bone of antlers to compact bone can be stimulated by administra-tion of oestrogens and previous work has demonstrated the presence of specific oestrogen binding in this tissue. In this study the presence of oestrogen receptors (ER) in antler tissue from red deer males was exam-ined by immunocytochemistry using a monoclonal mouse anti-human ER serum. Strong positive staining was detected in the tip regions of immature antlers and was confined primarily to the cells forming a fibrous layer of the perichondrium. This finding indicates that the effects of oestrogens on remodelling of cancel-lous bone of the antler may be mediated indirectly by the surrounding connective tissue layers.

The fern flora of the Seychelles archipelago remains relatively poorly known. Current projects involving the development of the Seychelles National Herbarium and study of key biodiversity areas have resulted in extensive new explorations on the granitic islands. Historical literature, newly collected specimens and older collections have been revised for the fern family Marattiaceae as a prelude for a fern checklist, resulting in the rediscovery of Ptisana a century after it was last reported (as Marattia). Two species of Angiopteris are recognised in the Seychelles, one of them new to science. In total, three species are recorded from the granitic Seychelles islands, Mahé and Silhouette, and none from the coral islands, which are too dry to harbour Marattiaceae. These three species are described in detail. The newly described Angiopteris chongsengiana is characterized by the elongated terminal pinnules and progressively reduced distal pairs of pinnules. Based on phylogenetic molecular analyses the Ptisana fraxinea complex is discussed and several new combinations are proposed. The Seychellois Ptisana is most closely related to Ascension Island endemic P. purpurascens and is described as a new species, Ptisana laboudalloniana. It differs from P. fraxinea in its winged secondary rachises and from P. salicifolia in its smaller habit, with the laminae shorter than broad and shorter than the petioles. Preliminary revisions of other fern families indicate that more discoveries are likely to be made in the fern flora of the Seychelles.

An expanded description of Salvia platyphylla with new insights based on the examination of recent herbarium specimens and observations made in the field is provided. Additionally, are included descriptions and illustrations of two new species morphologically similar to S. platyphylla. The first, S. pugana, can be distinguished from S. platyphylla by its larger calyces, magenta corollas with larger and internally epapillate tubes, longer filaments and connectives, and wider nutlets. The second, S. albiterrarum, differs from the latter by its longer corolla tubes, absence of patent white nectar guides on the lower lip, longer filaments, longer and not geniculate connectives, longer styles, with the branches and 3–5.3 mm of the apical portion exserted from the upper lip, and lower stigmatic branch straight rather than sigmoid or arquate. The three taxa are sympatric and represent western Mexico endemisms. Lastly, floral morphology differences between these species suggest valuable considerations on pollination syndromes.
