 In 1987 , the British ornithologist Graham S. Cowles prepared a manuscript that described a new species of Old World babbler , Rodriguites microcarina , based on an incomplete sternum found in a cave on Rodrigues . In 1989 , the name was mistakenly published before the description , making it a nomen nudum . Later examination of the sternum by Hume showed that Rodriguites microcarina was identical to the Rodrigues starling .
