. The Canadian field-naturalist. 1993 Goodchild: Status of the Tessellated Darter 425. Figure 2. North American distribution of the Tessellated Darter, Etheostoma olmstedi, from Lee and McAUister (1980). utaries (Figure 4). In Quebec and in the Lake Ontario region the ranges of the Tessellated Darter and Johnny Darter are largely sympatric but ecologi- cally distinct. From the St. Lawrence River, the Tessellated Darter has been reported as far northeast as Quebec City at St. Foy, Quebec (Lee and McAllister 1980) and recently just downstream from Quebec City, near the Boyer River, Bellechasse, Quebec [ROM 41917]. It has been collected extensively and evidently is well established in many of the tributaries to the St. Lawrence River in both Quebec and Ontario. The Tessellated Darter extends upstream in the Ottawa River to Little Bay [Canadian Museum of Nature, Ottawa (NMC), NMC 80-0910]. Addi- tionally, it is found in other larger rivers of the area such as the Mississippi and Rideau. McAllister and Coad (1974) suggest that it is usually replaced in smaller rivers of this area by the Johnny Darter. However, the Tessellated Darter has also been col- lected in several smaller streams tributary to the Ottawa River such as the Little Carp River, Cody Creek, Brassils Creek, and Dales Creek [NMC 68- 2104, 68-0310, 58-0315; ROM 11154]. Until recently, Etheostoma olmstedi was not well known from the Canadian tributaries to Lake Ontario. Collections by the Ontario Ministry of Natural Resources (OMNR) and the ROM in the 1970s and 1980s can be summarized as follows: the Bay of Quinte and Prince Edward County, west to Salem Creek and Smithville Creek in Northumberland County, west to Bowmanville, Frenchman's Bay and the Toronto Harbour [ROM 04881, OMNRS64, ROM 35110, AOCMNR86, ROM 36533, AOCMNR86, AOCMNR87]. Furthermore, E. olmstedi has been collected west of Lake Ontario, in Forty Mile Creek, tributary to the south shore of Lake Ontario [ROM 37338 and 38037] and at the mouth of
