The genus Habronema has four valid species, of which only two are properly known. The present study aimed to describe in detail the morphology of Habronema clarki through optical and scanning electron microscopy analyses. Our results showed that the labial morphology of this parasite is closer to H. muscae than to H. microstoma. Even so, the characteristic pseudolabia and the slightly convex border of the dorsal and ventral lips are sufficient to distinguish these nematodes. Additional morphological data are presented, thus contributing to the knowledge on this little known nematode. In addition, this study provides new locality records for this species.

If readers of Great Plains Research are seeking a window on rock art research in North America, this book provides a few clear panes, a few that are hazy, and a few muddy ones. Like many edited volumes, the weaker contributions and lack of a consistent style limit the book's usefulness. Some authors target a general readership; others clearly are addressing colleagues. The book has two stated themes: the history of rock art research in North America and recent approaches to rock art analysis. Articles by Julie Francis and (jointly) David Whitley and Jean Clottes explore why rock art research has long been marginalized in North America. Unfortunately, both of these otherwise observant essays slip into advocacy of shamanism as a unifying or primary explanation for rock art, an interpretive model by no means universally accepted by today's rock art specialists.

As an undergraduate sociology major, the only thing I learned about Oklahoman Laud Humphreys's classic, Tearoom Trade (1970) was how it violated standards of informed consent in social science research. As Galliher, Brekhus, and Keys recount in their biography, Laud Humphreys: Prophet of Homosexuality and Sociology, sociology graduate student Laud Humphreys needed to supplement his (quite likely, participant) observational research of men who had sex in public bathrooms (i.e., tearooms) in St. Louis in the mid-1960s with a formal questionnaire. Knowing that these men would never agree if they knew they were selected because of their participation in highly stigmatized and criminal behavior, Humphreys recorded their license plates, got their home addresses, and interviewed them as part of a "community health survey." Herein lies the deception and the major source of the controversy. What I didn't fully appreciate when I was a student, however, and what the authors so deftly illuminate is the importance of this work not only for debates around ethical issues of social science research, but more importantly, perhaps, for the study of sexuality, deviance, and urban life.

The spotted paca is the second largest rodent in Brazil, where it is of great economic interestin impoverished regions in view of its prominence as a low-cost source of protein. Littleis known about the morphology of the accessory genital glands of this species. Thus, westudied the position and morphology of the genitals in ten adult male spotted pacas. Theanimals were divided into two groups, five animals were used for fixing of samples in 10%aqueous formaldehyde for macroscopic studies and the other five animals were designatedfor microscopic analysis. These were arranged in pairs and had the vesicular, prostate,coagulating and bulbourethral glands identified, being structured as mucous glands, whichlead into the pelvic urethra. It was concluded that the accessory genital glands found in thepaca are the same as those found in most rodents, showing similar histological aspects
