Several lots of unidentified crabs assigned to Potamidae, Gecarcinucidae, and Sesarmidae from the Malay Peninsula and Northern Borneo were examined from material deposited in the reference collections of the Natural History Museum, London. While most of the species have been reported elsewhere, there are some new locality records, and surprisingly, two undescribed species of Isolapotamon Bott, 1968, a relatively well-studied Bornean-Philippine endemic potamid genus.

Crocodilians show a wide range of maximum Total Length (TL) and Crocodylus porosus is considered one of the largest crocodilian species with some individuals attaining more than 6 m in length. Remains of such exceptionally large crocodiles are sometimes found in different countries although details of these individuals such as TL, origin, or date of acquisition have been lost in many cases. Here we measured two exceptionally large but little known skulls found at the Lee Kong Chian Natural History Museum in Singapore and compared their morphological measurements to other large skulls reported from different countries. We found out in literature that one of the skulls, named “Edgar”, had been from one of the largest crocodiles ever reported (6.7 m TL) and brought from Java to the museum in 1887. Details of the other skull, named “Giryu”, still remain unknown. Based on the morphological measurements we presented here, it is likely both these crocodiles were C. porosus larger than at least 6 m TL. Given that such large individuals are hardly seen today due to previous hunting and habitat loss, these skulls have significant, biological and cultural values.

The polychaetes (Annelida) of Indo-Malay-Philippines Archipelago (IMPA) are poorly known taxonomically as a result of a lack of systematic collections, the dispersed nature of the collections throughout the world, and the lack of knowledge on the whereabouts of the type material. This has hindered both taxonomic studies on the group and, ultimately, biodiversity comparisons with other species-rich marine groups. In this study, we trace the history of scientific discovery of polychaetes and allied forms from IMPA. We find that the polychaetes and allies of the IMPA are described in a vast literature spanning almost 300 years, covering three main periods: shore collecting by the first European colonisers during the seventeenth to end of the nineteenth centuries, deep-sea collections from nineteenth and twentieth century European voyages of discovery, and post-1960s bilateral and multinational collaborative voyages and expeditions. A comprehensive bibliography of relevant literature is produced and the fate of the polychaete specimens collected discussed.

Sunda swamp eels are air-breathing fishes that are able to live out of water for extended periods of time, and can even survive drought if buried in moist holes in the ground. Because swamp eels shelter in burrows during the day, and only emerge at night to hunt for prey that includes fish and frogs, they are rarely seen (Munro, 1990: 109 as Monopterus albus). In Singapore, the swamp-eel is widespread and inhabits most types of freshwater and even brackish water bodies, from forest streams to monsoon canals in urban areas. It is also tolerant of some amount of pollution in its habitat (Lim & Ng, 1990: 84; Baker & Lim, 2012: 42; as Monopterus albus). The swamp-eel is sought after as a food fish in Malaysia and Singapore. It is regarded as a very tasty fish with supposed medicinal value particularly by the Chinese and Thai people (Mohsin & Ambak, 1983: 178; Lim & Ng, 1990: 84; as Monopterus albus).
