Pletsch and Orr: Tng/ops dorolhy, a new species from the southern Sea of Okhotsk 



243 



p = number of pectoral-fin rays; 

 df = number of dermal folds; 

 io = interorbital width divided by SL; and 

 // = number of lateral-line scales. 



All individuals with negative scores had been previ- 

 ously identified as T. dorothy, whereas those with posi- 

 tive scores were T. pingeli. The discriminant function 

 equation correctly classified all individuals, as did the 

 cross-validation procedure. 



Distribution and habitat 



Triglops dorothy is known only from the southern Sea of 

 Okhotsk: 19 specimens collected in or adjacent to Aniva 

 Bay, at the southern end of Sakhalin Island, Russia; and 

 two specimens from north of Kitami, Hokkaido (Fig. 4). 

 The material was trawled off bottoms of mud, fine sand, 

 rock, and clay, at depths of 73-117 m. 



Etymology 



The species is named in honor of Dorothy Thomlinson 

 Gilbert, great granddaughter-in-law of the eminent 

 ichthyologist and fisheries biologist Charles Henry Gil- 

 bert, for her generous and steadfast support to graduate 

 students in ichthyology at the University of Washington, 

 Seattle, in establishing the William W. and Dorothy T.

 is to be treated as a noun in apposition. 



Discussion 



Credit for the discovery of T. dorothy is given to Charles 

 Henry Gilbert (Pietsch, 1993; for biographical infor- 

 mation on Gilbert, see Dunn, 1997), who, soon after 

 the material was collected, recognized its uniqueness.
