Two new haemogregarine species, Hepatozoon langii n. sp. and Hepatozoon vacuolatus n. sp., are described from the pe-ripheral blood of the high altitude crag lizard, Pseudocordylus langi, collected between October 2006 and April 2009 from the North Eastern Drakensberg, Eastern Free State. Hepatozoon langii n. sp. has maturing and mature gamonts that appear encapsulated and have narrow, curved tails. Their cytoplasm stains pinkish-purple with Giemsa, while their nuclei are pur-ple stained with stranded chromatin. Mature gamonts measure 19.1 ± 1.0 (15.4–28.1) μm long by 6.2 ± 1.1 (3.5–7.9) μm wide. Hepatozoon vacuolatus n. sp. gamonts are mostly broader at one pole than the other, have bluish-pink cytoplasm characterised by distinctive rounded and oval vacuoles, and demonstrate pink granules with Giemsa staining. Nuclei stain purple and are mainly coarsely granular. Mature gamonts measure 16.5 ± 1.0 (14.7 - 17.6) μm long by 5.9 ± 1.2 (4.0 - 7.7) μm wide. Both species parasitize erythroblasts, as well as erythrocytes and can dehaemoglobinize the cytoplasm of their host cells. Hepatozoon langii n. sp occurred in the absence of H. vacuolatus n. sp., but the latter haemogregarine always formed mixed infections with the former; no stages intermediate between the two haemogregarine types were observed.

This paper sets out to profile optometric gradu-ates in South Africa. The 2008 register of the Health Professions Council of South Africa (HPCSA) was used to identify the number of registered optometrists, their qualifications and institutions where they obtained their primary optometry qualification. The gender and racial profiles of these optometrists were obtained from the institutions where they qualified. A comparison of the profiles ofthe registered practitioners pre-democracy (1930-1994) and post-democracy (1995-2008) was made. Few (28.1%) of the optometrists were trained in the years 1930-1994, while the rest (71.9%) were trained from 1995-2008. During the period of1930-1994, 64.2% of the optometrists were males and 35.8% were females and from 1995 to 2008, the gender profile changed to 66.4% females and 33.6% males. In the pre-democracy period (1930-1994), almost three quarters (74%) of the registered optometrists were White, 15.3% were Indians, 7.9% were Black and 2.8% were Coloured. Many (56.9%) that were registered pre-1994 were trained at the Technikon Witwatersrand (TWR), 17.1% were trained at the University of Durban Westville (UDW), 11.9% at the Rand Afrikaans University (RAU), 6.7% at the University of the North (UNIN) and 7.4% had trained in institutions outside South Africa. The percentage of White optometrists post-democracy (1995-2008) decreased to 44.3%, while those of Indians increased to 22%, Blacks increased to 28.9% and Coloured to 4.8%. Almost half (48.2%) of the optometrists in the post-apartheid era (1995-2008) were trained at the University of Johannesburg (UJ), TWR and RAU, 21.5% at UDW and University of KwaZulu-Natal (UKZN), 23.7% at UNIN and the University of Limpopo (UL), 4% at the University of Free State (UFS) and others (2.6%) had trained outside South Africa. As at 2008, the majority (51.7%) of all registered optometrists were White, 22.2% were Black, 21.9% were Indian while 4.2% were Coloured and included 57.8% females and 42.2% males. The results of this study indicate that the number of females in all racial categories has increased post-democracy. Although the number of Black optometrists has increased in the post-democracy era, the increase does not yet reflect the national population distribution. Optometry departments need to improve on the equity targets.(S Afr Optom 2011 70(3) 123-128)

The distributions of endemic tick vector species as well as the presence of species not endemic to Free State Province, South Africa, were determined during surveys or opportunistic collections from livestock, wildlife and vegetation. Amongst endemic ticks, the presence of Rhipicephalus appendiculatus was confirmed in the north of the province, whilst Rhipicephalus decoloratus was collected at 31 localities mostly in the centre and east, and Ixodes rubicundus at 11 localities in the south, south-west and centre of the province. Amongst the non-endemic species adult Amblyomma hebraeum were collected from white rhinoceroses (Ceratotherium simum) on four privately owned farms, whilst the adults of Rhipicephalus microplus were collected from cattle and a larva from vegetation at four localities in the east of the province. The collection of Rhipicephalus evertsi mimeticus from a sheep in the west of the province is the second record of its presence in the Free State, whereas the presence of Haemaphysalis silacea on helmeted guineafowl (Numida meleagris) and vegetation in the centre of the province represents a first record for this species in the Free State. The first collection of the argasid tick, Ornithodoros savignyi, in the Free State was made from a domestic cow and from soil in the west of the province. The localities at which the ticks were collected have been plotted and the ticks’ role in the transmission or cause of disease in domestic livestock and wildlife is discussed.

Within the group of islands which together comprise Spitsbergen outcrops of dolerite may be traced over an area of about 50,000 square miles. The area is doubled if the neighbouring dolerites and basalts of Franz Josef Land are included. Even so, this is but a part of a network widely spread over the north-western part of the Euro-Asiatic continental platform, and over adjoining circumpolar lands. The sill-swarms of Spitsbergen alone rival in extent any of approximately similar age in other parts of the world, such as those of South Africa, South America, India, Antarctica, or North Britain. They merit a great deal more attention than it has yet been possible for geologists to devote to them.
