Karl Shuker's blog has a recent post on water elephants of the Congo, which gives a plug to "British cryptozoological investigator Matt Salusbury in his extremely comprehensive book Pygmy Elephants (2013)" Dr Shuker feels that "if this cryptid has been described accurately in those sightings... its morphological differences from Africa's typical, predominantly terrestrial elephants are, I feel, much too profound" for it to be any member "Africa's modern-day Loxodonta species" and that it would have to be something altogether different, possibly some much more ancient relatives of the modern elephants, long thought extinct.
Fortean Time's reviews editor confirms that Karl is on the case with a review of Pygmy Elephants, which will appear shortly in FT.
Karl is also on the case with his own "enigmatic but seemingly long-lost specimen, the Rothschild-Neuville mystery tusk" and will publish something on this in his blog soon. Followers of the Pygmy Elephants Twitter feed will know I am also on the case with this, and will present a talk on it at this year's Weird Weekend. There's a lot of crowdsourced assistance coming in from the zoology and paleontology communities, particularly on museum accession logs.
