Megalobatrachonema (Chabaudgolvania) elongata (Baird, 1858) n. comb, is redescribed based on specimens from Ambystoma tigrinum, A. lacustris, Ambystoma sp., and Rhyacosideron altamirani (Ambystomatidae) from various localities in Mexico. The species is transferred to Megalobatrachonema from Falcaustra because the oesophagus lacks valves and the oesophageal bulb is reduced in size. Megalobatrachonema (C.) elongata may be differentiated from the only other species in the same subgenus, M. (C.) terdentatum (Linstow, 1890), from Triturus spp. (Salamandridae) of Europe, by differences in oesophageal and cephalic morphology, and the distribution of caudal papillae in males.

Purpose The original Connected Speech Test (CST; Cox et al., 1987) is a well-regarded and often utilized speech perception test. The aim of this study was to develop a new version of the CST using a neutral North American accent and to assess the use of this updated CST on participants with normal hearing. Method A female English speaker was recruited to read the original CST passages, which were recorded as the new CST stimuli. A study was designed to assess the newly recorded CST passages' equivalence and conduct normalization. The study included 19 Western University students (11 females and eight males) with normal hearing and with English as a first language. Results Raw scores for the 48 tested passages were converted to rationalized arcsine units, and average passage scores more than 1 rationalized arcsine unit standard deviation from the mean were excluded. The internal reliability of the 32 remaining passages was assessed, and the two-way random effects intraclass correlation was .944. Conclusion The aim of our study was to create new CST stimuli with a more general North American accent in order to minimize accent effects on the speech perception scores. The study resulted in 32 passages of equivalent difficulty for listeners with normal hearing.
